Hard membrane switch means that the pattern and circuit of the switch are made on a common printed circuit copper clad board.

Hard membrane switch Advantages: Easy access to materials, stable process, low resistance, and direct soldering of certain components in the circuit on the back side. In the case of a small area, the hard liner layer can be omitted. Hard membrane switches generally use metal guides as conductive labyrinth contacts, and therefore have a better handle.

Disadvantages of the rigid membrane switch: It is convenient to install the flexible membrane switch in the whole machine. It is often necessary to solder the plug and lead the wire through the flat cable.
