Capacitive Switch
No moving parts, no wear, no pressure needed. CP Series capacitive switches sense fingertip touch through sealed stainless faces — 16mm to 25mm, built for millions of activations.
Capacitive Switch Products
-
16mm Capacitive Switch
Our 16mm capacitive buttons are designed for durability and require low activation force, making them as sensitive as a touch screen. These features make our capacitive buttons ideal for industrial applications where repetitive activation can cause operator fatigue. -
19mm Capacitive Switch
Discover LANGIR's high-performance 19mm capacitive touch buttons. With cutting-edge sensing technology, our durable switches are suitable for diverse industries like industrial automation, medical equipment, control panels, etc. -
22mm Capacitive Switch

Why Choose Langir Capacitive Switches?
The CP Series replaces mechanical actuation entirely: touch the sensing surface and the switch's electric field detects your finger, activating the circuit with zero physical movement. Nothing flexes, nothing wears, nothing traps dirt — which is why these switches deliver exceptional service life and completely smooth, cleanable faces. Offered in 16mm, 19mm, 22mm, and 25mm bushing sizes with sealed stainless construction, they suit hygiene-critical medical equipment, food processing lines, modern kiosks, and premium product designs where a light touch and flush aesthetics define the user experience.
Frequently Asked Questions About Capacitive Switches
Technology, sizing, and application guidance for the CP Series capacitive range.
It senses the change in its electric field when a fingertip approaches the surface, generating a switching signal without any mechanical movement or applied force.
Four bushing diameters — 16mm, 19mm, 22mm, and 25mm — letting capacitive technology slot into the same cutouts as conventional Langir switches.
Sensitivity is engineered to discriminate a fingertip from water films; combined with sealed construction, this makes CP switches viable outdoors and in washdown areas.
Thin gloves such as medical nitrile typically work; thick insulating gloves may not activate the sensor. For heavy-glove environments, consider our piezo or mechanical ranges.
Capacitive needs only proximity touch — no pressure at all — giving the lightest possible user interaction and zero mechanical stress on the panel.
