PET Flexible Membrane Switch

A membrane switch or flat switch consists of a printed polyester or polycarbonate overlay that adheres to a printed circuit, using pressure to open and close the circuit. A HMI non-tactile membrane switch is considered a "momentary action" switch, meaning that the switch is essentially always on, but when the switch is pressed, the circuit is temporarily closed, activating the key function.

Principal Types of PET Flexible Membrane Switch

PET-based membrane switches can be realised in multiple configurations:

Flat-surface PET switches: Key areas lie flush with the panel, offering a clean aesthetic and the lowest cost.

Convex PET switches: Key areas are raised through thermoforming, providing optimal tactile feedback and representing the most prevalent type.

Tactile PET Switches: Incorporate metal springs within the PET membrane structure to deliver a distinct “click” sensation.

LED-Backlit PET Switches: Integrate LED lighting within the circuit layer, with light uniformly diffused through the transparent PET material to achieve backlit indication.
