Capacitance tactile switch
max. 0.95" (24 mm) Esterline Interface Technologies

TrueTouch is switching technology based on the principle of signal detection through capacitance or resistive coupling (human touch) of identified generated input pulses.

The touch surface can be designed with virtually any dielectric material including glass, plastic, polycarbonate, or any rough or smooth surface less than 25mm thick. Sensitivity is adjustable allowing operators to actuate the device with or without gloves. Because there are no moving parts, a TrueTouch switch is rated for more than five million cycles.

TrueTouch technology provides cost-effective design alternatives to other switch technologies. Open architecture allows for easy integration or retrofit into a wide range of switch applications.
