Capacitive Switching

 

TrueTouch Capacitance Switching     

Capacitive switching technology is 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 capacitance switch is rated for more than five million cycles.

Capacitance switching 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.
