A membrane switch is a momentary on/off switch for many different circuits. Membrane switches are thought to be momentary because they operate normally open, push to close, and immediate opening conditions. What this means is that once the switch is pressed, the two poles within make contact to close the circuit. Membrane switches are used in many industries, ranging from medical and commercial applications to consumer markets. Membrane switches are made by printing silver or carbon ink onto polyester film and then an overlay is applied to the first surface as the graphics interface.

There are two types of membrane switches: tactile and non-tactile. A tactile membrane switch relies on the user’s touch to connect the switch and underlying control panel. When pressed, the user may feel a snap of the switch. Tactile switches are used for instruments, interface control-panel applications, and keypads.

A non-tactile membrane switch is intended Continue reading
