Capacitive Touch Switches and Panels
Custom capacitive touch switches, keyboards and panels based on capacitive coupling. No mechanical parts, long life, backlit glass finish and easy disinfecting for medical, kiosk and industrial use.
What Are Capacitive Sensing Switches?
A capacitive sensing switch works on capacitive coupling and takes input as human-body capacitance - the same principle as a smartphone touch screen. Touch transfers a small charge to the switch, capacitance changes, and the switch answers with the right command.
Backlit glass gives vivid graphics and an elegant look, while the printed glass over the PCB means users never touch metal directly - a real safety plus. With no mechanical parts there is almost no wear, life is long, and disinfectant wipedowns make these ideal where hand hygiene matters.

Good to Know Before You Enquire
Three facts that shape your exact quotation.
Touch transfers a small electrical charge from the body to the switch, capacitance on the pad changes, and the sensor responds with the matching command - no pressure needed.
No mechanical components means long life, while backlit glass delivers strong graphic clarity and an elegant finish for indoor, kiosk and industrial builds.
Trusted by makers of home automation devices, public kiosks, self-service terminals, industrial automation, computer peripherals and consumer electronics.
