Capacitive switch

Capacitive switch

Capacitive switch 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 switch 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.

The CP Series Capacitive switch technology senses the touch of a finger and creates an electrical charge to activate the switch. An auto-calibration function ensures the sensor adapts to changing external environments.
LANGIR’s capacitive switch are specially designed for durability and a low activation force. As sensitive as a touch screen, the capacitive switch are perfect for industrial applications where repetitive activation can cause operator fatigue.


  • Activated by the easy touch of a finger, the capacitive switch extremely to use
  • Adjustable sensitivity sensor adapts to external environments
  • Easy-to-locate or on/off indication is possible through independent or output image LED functionality
  • Easy to clean because the switch is impervious to dust and dirt, and resistant to harsh chemicals and contaminants
  • 50 million cycles and no moving mechanical parts make LANGIR’s CP switches robust and durable
  • Available in momentary or latching and with or without illumination
