Membrane Switches
overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
Membrane switches are a type of electronic switch that uses a flexible membrane layer to perform electrical contacts when pressed. They typically consist of multiple layers, including a graphic overlay, spacer, and circuit layer, which work together to provide a sealed, reliable input interface often used in consumer electronics, appliances, medical devices, and industrial controls.
