Membrane Switches Overview
What are Membrane Switches?
The ASTM subcommittee on Membrane Switches defines a membrane
switch as: "A momentary switch device in which at least one
contact is on, or made of, a flexible substrate".
To be more specific, all of the following conditions or features
must be met in order to truly be classified as a membrane switch:
- Direct (Ohmic) Contact: the poles of the switch must make physical
contact, i.e. can not be non-contact type like capacitive, ferrite
core, or hall effect.
- Momentary Action: Upon release, the poles immediately separate
as the flexing membrane returns to its original position.
- Low Voltage Application: A membrane switch is designed to be
used in low voltage, DC logic-level-signal, applications.
- Membrane Layer: A thin pliable layer and carries one pole,
both poles or that flexes during switch operation used to short
both switch poles together.
- Static Layer: Does not flex during switch operation but carries
one pole, both poles or used to short both switch poles together.
Membrane switches are used for user input to control a machine,
computer or other electronic device. Membrane switches are ideal
for harsh industrial environments.
