The PC-Trac Switch Adapted trackball from Clearly Superior Technologies offers alternative clicking options available to users who may struggle with fine motor control. It features 3 jacks which permit the attachment of external control switches which can be placed where best suited to the needs of the individual user.
All of the features of the basic PC-Trac—high density 2.5" diameter phenolic trackball for tactile feedback and smooth response, light touch buttons, safely secured trackball, low profile housing, ambidextrous feature, 'Dynamic Acceleration', Drag Lock and Scroll Lock—are available on the Switch Adapted version.
The extra-large size, low activation force and large dimensions of the buttons also mean that anyone with limited strength will be able to perform clicks as easily as any user.
Users who have vision limitations may wish to consider the high visibility KidTrac Switch Adapted or the high performance L-Trac Switch Adapted versions which feature white housings with yellow trackballs and red, blue, and green buttons.
Uses Less Space Than Conventional Mice
- The stationary nature of the PC-Trac Switch Adapted trackball also allows the user to conserve space on their workspace. It is ideally suited for space restrictive environments or narrower keyboard trays that can accommodate a keyboard with only a few inches extra to spare.
Reduces Strain on Arm, Elbow and Shoulder Muscles
- Like a touchpad, PC-Trac Trackballs are stationary mousing devices. (Moving the ball with the fingers moves the cursor on the screen.) Limiting the repetitive movements of the arm and shoulder can greatly reduce the potential for injury and inflammation in these muscle groups. The housing of a trackball can also be angled in any direction, allowing the user to keep the elbow, wrist and hand in a straight line, and to limit ulnar and radial deviation.

Reduces Strain on the Hand, Wrist and Arm
- Trackballs effectively counter any tendency the user might have to grip the pointing device too hard. This often inadvertent static grip can cause pain and injury to the muscles and soft tissues in the back of the hand and in the wrist and forearm. Trackballs, by requiring a simple spinning motion accomplished with the fingers, eliminate static grip entirely. Learn More About Static Grip Force
Reduces Reach for Buttons
- PC-Trac Switch Adapted Trackballs have large oversized buttons surrounding the trackball, allowing users to use whichever finger minimizes reach and strain when pressing buttons. The available customizing software (Pro model only) allows the assignment of functions to whichever button the user desires.
Hardwired Drag Lock Feature Reduces Finger Fatigue
- The hard-wired drag-lock feature (the non-Pro versions of the PC-Trac) allows users to activate drag-lock by simply clicking on the middle button without having to hold down the button while dragging the selected item on the computer screen. This will simplify using applications that require significant click-and-drag actions. The non-Pro models also have a scroll-lock feature that allows users to horizontally and vertically scroll without having to hold down a button. By not having to continually hold down the button while dragging with the mouse, finger fatigue can be greatly reduced.
Enables Load Balancing Between Left and Right Hands
- PC-Trac Trackballs feature an ambidextrous design and can be placed on the left or right side of the keyboard in the traditional desktop layout. They can also be used between the two modules of a separated keyboard, on the arm of a couch, or wherever else the user might find convenient and comfortable. The ability to distribute the workload as desired allows the user to reduce the strain on the muscles of the dominant side. The PC-Trac Switch Adapted model makes this easy by offering a special 'Ambidextrous Trackball' feature which allows fast switching from left to right-handed use by simultaneously pressing all 3 buttons, without the need to change system settings.
Large Diameter Weighted Ball
- The 57 mm ball on the PC-Trac Trackballs is weighted to provide users with excellent response feedback. With the PC-Trac there is no accidental movement as users have exceptional control. The weighted ball also supports rapid movement which enables users to adjust cursor position with exceptional speed.
Dynamic Acceleration Reduces Repetitive Movement
- The Dynamic Acceleration feature incorporated into all PC-Trac models is especially beneficial to users working with large high resolution screens or those who need to rapidly move the cursor across greater distances. This feature ties the distance travelled to the speed with which the ball is rotated. For example, a 1/4 rotation of the ball at a rapid rate will cause the cursor to cover a substantially greater distance than the same 1/4 rotation performed at a slow rate. This can be especially beneficial for uses (such as CAD) where exceptional accuracy is required at one moment while still needing to move larger distances the next. Users are able to set the resolution of the trackball to a lower setting in order to achieve a greater degree of control, yet with a rapid movement of the ball can still cover the greater distances necessary for accessing menus. A fixed acceleration trackball would require a greater degree or number of rotations in order to cover these larger movements, resulting in an increase in the amount of necessary finger movement.
- Middle Button Hard-wired to Drag-Lock: The middle button is a drag-lock - this means that there is no need to hold a button down to highlight, select or drag an item. This is a real plus for individuals with trigger finger, who constantly have to click, or for those with motor skill difficulties.
- Switch Adapted Model: The PC-Trac Switch Adapted Trackball is a three button device that includes three 3.5 mm external switch jacks. Users can plug in any standard assistive switch to generate the 3 different button actions corresponding to the regular buttons (left click, middle click, right click). Once an external switch is connected the onboard switch is disabled to reduce or eliminate accidental clicking while the trackball is being used. These specialized switches can then be positioned where best suited to the needs of the specific user. There are a variety of Switches which can be used with the SA models of the PC-Trac, KidTrac, or L-Trac trackballs.
- Middle Button in Scroll-Lock Mode: The middle button can also act as a scroll-lock. To have the button perform a scroll-lock (instead of the default drag-lock), press and hold the button for 3 seconds and it goes into scroll-lock mode. To leave scroll-lock mode, press any button again.
- Dynamic Acceleration: The Dynamic Acceleration feature incorporated into all L-Trac models is especially beneficial to users working with large high resolution screens or those who need to rapidly move the cursor across greater distances. This feature ties the distance travelled to the speed with which the ball is rotated. For example, a 1/4 rotation of the ball at a rapid rate will cause the cursor to cover a substantially greater distance than the same 1/4 rotation performed at a slow rate. This can be especially beneficial for uses (such as CAD) where exceptional accuracy is required at one moment while still needing to move larger distances the next. Users are able to set the resolution of the trackball to a lower setting in order to achieve a greater degree of control, yet with a rapid movement of the ball can still cover the greater distances necessary for accessing menus. A fixed acceleration trackball would require a greater degree or number of rotations in order to cover these larger movements, resulting in an increase in the amount of necessary finger movement.
- Universal Compatibility: The universal compatibility of this design means it works well in a multi-user environments with a range of individuals.
- Low Profile: The PC-Trac Trackball has a low profile case that acts as a natural hand-rest, mirroring the natural contours of the hand.
- Robust Design: Employing strong ABS plastic construction, a virtually indestructible phenolic trackball and stainless steel rollers, Clearly Superior Trackballs are designed with durability a key consideration.
- Large Weighted Trackball: The large 57 mm ball provides increased accuracy and control. The weight also enables rapid movement across large distances as it can be "spun".

- If the intent is to use this with adaptive switches be careful when making your selection. It is important that switches with appropriate activation force levels are chosen. As well, consider the overall footprint required for the external switches to ensure that they can be placed within suitable reach.
- If you are new to a trackball expect that it will take a while to get accustomed to the different style of control. It is also a good idea to limit the amount of time you use it in the first while. Rather, build up to longer periods of usage by interchanging with a different mousing device or by Load Balancing (see next point).
- Load Balance Your Use: The freedom of an ambidextrous trackball lets you easily switch between left and right handed use. Make a point of using it with your non-dominant hand. Not only is this good for your dominant hand, which gets a break from working, it can slowly build dexterity and endurance which your non-dominant hand generally does not have. As a bonus, it is also a way of stimulating the other half of your brain, which is never a bad idea. The PC-Trac Switch Adapted Trackball encourage ambidextrous use with a special "Ambidextrous Trackball" feature which allows fast switching from left to right-handed use by simultaneously pressing all 3 buttons, without the need to change system settings.
- Take Regular Breaks: If you find that you are experiencing discomfort in your fingers, especially in the learning stages - that is a good sign that you may want to take a break by switching to a different device or by swapping to the other hand. As with any device, make an effort to regularly change your usage, take breaks, and perform stretches. Some users find that the fingers can benefit from occasionally flexing them through a full range of movement, both extending and contracting them fully.
- Employ the 'Dynamic Acceleration' feature to reduce unnecessary repetitive rotation movements when needing to move across large distances. Moving the ball quickly will cause it to cover a much greater distance than it will if rotated slowly for the same amount of rotation (i.e. a quarter of a rotation at a higher speed will cover a much greater distance than a quarter of a rotation at a slow speed).
