Working Principle
Membrane switches operate as momentary contact switches, meaning the circuit only conducts when pressed and disconnects upon release.
Normal State (Unpressed): Supported by the isolation layer, the contacts of the upper and lower circuit layers remain physically separated, maintaining an open circuit.
Actuation: When a finger presses the panel layer, the applied pressure deforms the upper circuit layer. Its contacts then penetrate the openings in the insulating layer, making contact with the lower circuit layer's contacts. This completes the circuit, triggering an output signal.
Release: Upon releasing the finger, the elasticity of the thin-film material causes the upper circuit layer to rebound. The contacts separate from the lower circuit layer, restoring the circuit to its open state.
Advantages of membrane switches:
Ultra-thin and lightweight: The overall thickness can be achieved within 1mm, making it highly suitable for modern equipment with stringent space requirements.
Fully sealed: The panel layer consists of a single sheet of film, effectively preventing dust, grease, and moisture from entering the machine through key gaps, offering high protection ratings (typically up to IP67).
Aesthetic Durability: Printed patterns resist wear, offer rich colour options, and allow flexible design, significantly enhancing product visual appeal.
Cost-Effectiveness: Relatively low production costs are achievable during high-volume manufacturing.
Flexibility: Utilising flexible circuit technology, it adapts to moderately curved surfaces.
