The L-Trac Switch Adapted from Clearly Superior Technologies features the high performance and robust build for which the original PC-Trac line is well-known. The L-Trac features an optical laser sensor which offers "button selectable" tracking resolutions of 400, 800 and 1600 CPI, easily changed on the fly. Combined with this is the ability of the L-Trac to track at speeds exceeding 30 inches per second, even at a 20G acceleration rate. The scroll wheel is smooth and readily accessible, located above the center button. Unique to the Switch Adapted version of the L-Trac is the availability of three jacks which support connection of external switches. Connecting an external switch deactivates the on-board switch for that function - a feature which can be of benefit when seeking to eliminate accidental button activation. This means that the click activations can be performed from alternate locations more advantageous to the user.

The L-Trac provides users with a precision, high performance pointing device. The large 57 mm diameter weighted trackball produces predictable, quick, and precise cursor control. Most users will find that movement becomes intuitive within a few minutes of use, with the level of control increasing over time.

The level of performance and range of features, coupled with the proven contour of the L-Trac makes these trackballs an appropriate option for all applications including general computing, gaming and Computer Aided Design (CAD). CAD users love it because you can drag a line one pixel even on high resolution displays. Then, with a button stroke, they can fly around the screen to get general tasks done. Gamers have called it an "almost unfair advantage", citing the fingertip control and precision, high performance tracking.

Designed to minimize the effects of contamination build up and the resultant degradation of performance, this high performance laser trackball uses highly polished stainless steel rollers. It has been found by CST that the "ruby ball sliders" used in most optical trackballs, cause performance degradation when gunk builds up on them. The L-Trac uses mirror polished stainless steel rollers that do not readily collect unwanted material and are easily cleared by spinning the ball rapidly. The Dupont Delrin bearings are embedded with Teflon and internally coated with a lifetime lubricant making the feel of this trackball extremely smooth and it's reliability very robust. The user-replaceable stainless steel rollers are extremely tough and designed to handle hard usage yet still provide users with controlled smooth movement.

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.
