What is the Difference Between Flexible Circuit and PCB Based Membrane Switches? When designing a membrane switch, one of the most critical aspects that must be decided early-on in the design stage is the circuit type. The whole design and construction of the part is based around the type of

What is Embossing in Membrane Switches?

Aug 15
Embossing in Membrane Switches To provide tactile feel to a membrane switch or graphic overlay, the material can be embossed to raise the key area. Embossing has really become standard in membrane switch designs. Not only does it give it a better look and feel, but it also allows the

How to Prevent Hot Spots in Membrane Switches

What are Membrane Switch Connectors? The connector on a membrane switch assembly is one of the most critical aspects of the machine interface as the connector attaches the membrane keypad to the product it will control. Without the connection working correctly the membrane switch is essentially useless. Connectors consist of
