What are Membrane Switches?

First of all, the most obvious question that can come to your mind is, “what are membrane switches?” These are basically momentary contact switches that are widely used in place of mechanical switch assemblies. It can also save a lot of PCB (printed circuit board) space and are extremely easy to operate.

Some features of membrane switchesare:

• Momentary Action – When released the poles separate as the flexing membrane returns to the former position.

• Direct Contact – The poles have to be in direct contact with each other. Hall Effect or ferrite core will not work in this case.

• Low Application of Voltage – You can’t use a high voltage source while using a membrane switch.

• Membrane Layer – A thin flexible layer is required that bends during switch operations and is used to short both poles together.

• Static Layer – As is evident from the name, this layer does not bend during switch operation and is used to carry one or both poles or short the switches together.

Nowadays, membrane switches are used extensively in membrane keypads. Keypads usually have separate parts but membrane keypads have symbols and letters embossed on a flexible surface. It is also referred to as a pressure pad. The reason for their popularity is because they come at a very reasonable price. Another advantage of these keypads is that they are more resistant to dust and liquids as compared to other keypads. This product has found various applications in calculators, microwave ovens, buildings that have restricted access, and even in remote controls. The LED (light emitting diode) technology helps in effectively backlighting any kind of text and graphics. Polyester dome switches of high temperature capacity can also be designed using membrane switch technology.
