Types of Membrane Switches
There are two main types of membrane switches, each performing a different function on the circuit board
touch. Tactile switches are designed to provide a response when pressed by an actuator or finger. Symbols or letters overlaid on the switches are used to designate the function of each switch. Typically, these switches feature a metal dome design. When pressed, the metal dome pushes against the conductive footprint, causing the action to occur.

non-tactile. This type of switch operates using the same concept as a tactile switch, but does not elicit a tactile response. The bottom of the overlay is connected to the conductive pad, and the non-tactile switch is a self-contained unit.

A membrane switch is a user interface device that is made up of several layers and used as a switch to turn a device on or off. Unlike mechanical switches, which are generally constructed with copper and plastics, membrane switches are printed circuits on film.
