TouchSensor Switch

TouchSensor patented the world’s only Field-Effect switch - a software free, solid-state switch.

The technology is setup as a “TouchCell™”. Each TouchCell™ consists of:

• One TS100 IC
• Electrode structure
• Two resistors for sensitivity selection

TouchCells™ are manufactured by TouchSensor on a rigid or flexible PCB. When 5 volts is applied to the TS100, an electric field is created. The field emanates through any dielectric substrate such as glass, plastic or leather. When a conductive mass enters the field, the sensor detects the change and indicates an event has occurred. The input stimulus to the field can take the form of the human finger, metal or liquid. We have used over 75 million TouchCells™ on our custom user-interface panels since 1999.

A TouchSensor keypad has a wide operating range, adjustable sensitivity, and is moisture and contaminant resistant. TouchSensor keypads are easily integrated into current and new interface designs with no need for electronic modification. Because no software is required, they are a direct, easy and aesthetic replacement for membrane and mechanical switches.
