About Capacitive Switch

Capacitive Switches

The new 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 switches are specially designed for durability and a low activation force. As sensitive as a touch screen, the capacitive switches are perfect for industrial applications where repetitive activation can cause operator fatigue.

Features:
Activated by the easy touch of a finger, the capacitive switches 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

Benefits:
Extreme ease of use/ Adaptable/ Easy-locate or on/off indication/ Easy to clean/ Robust and durable
