Tactile Membrane Switch

Tiantai Electronics is a leading China tactile membrane switch manufacturer and supplier. A “tactile membrane switch” is one type of widely used switch that completes an electrical circuit typically when pressure is applied to the device by the user, which then gives the user a perceptible “click” or haptic bump in response, indicating current flow. Current flow is turned off when the switch is released.

Metal Dome Tactile Membrane Switches: These switches feature a metal dome component design. When pressed, the metal dome deforms to contact the conductive layer below, completing the circuit. Upon release, the metal dome snaps back to its original shape, producing a “click” sensation for clear tactile feedback. Tactile membrane switch are durable and commonly used in environments requiring distinct feedback, like industrial control panels.

The purpose of a Tactile Membrane Switch is to deliver a physical and audible sensation upon actuation. When the switch is depressed, the switch typically responds with a ‘snap’, ‘click’, or ‘pop’. This is due largely to the type of actuator that has been adopted for the particular application.
