Membrane switches are also very good to use since they are effortless to use. A particular person only has to touch a button to activate the switch or deactivate the switch. Introduced on the marketplace about thirty years ago, the membrane keypad initially encountered a couple of obstacles, triggered in element by the restricted lifespan of the materials that have been employed at the time. In addition, what truly harmed the early improvement of this otherwise promising product was the disadvantage of its poor tactile response. Plastic domes can collapse due to extreme operating temperatures (higher and low) and should be limited to applications in controlled environments. The actuation force is also influenced by temperature, with higher temps generating very low actuation force and operator feedback, and low temperature actuation forces producing higher actuation force and a “crunch” sound and feeling to the operator. Style parameters for plastic domes are vital to their overall performance and durability. There is no recovery for a collapsed plastic dome when its geometry is compromised.

For this reason the really first project tackled by the Engineering Task Group of ASTM 1992 was defining a practice that did nothing else but depress and release a membrane switch to a predetermined number of cycles. Make contact with Closure Cycling, ASTM 1578, explains how to set up and expose a membrane switch to repeated closures. It does not have a measured outcome. In order to see the effects of repeated cycling you must measure a switch characteristic ahead of & soon after the cycling employing a various ASTM test method. i.e. Circuit Resistance ASTM 1680.
