This guide contains a list of the current test methods and practices generated by Subcommittee F01.18 on Membrane Switches along with typical values for specifying certain performance characteristics of a membrane switch.

Formerly under the jurisdiction of Committee F01 on Electronics and Subcommittee F01.18 on Membrane Switches, this guide was withdrawn in June 2009 because typical values have been and are being added to the individual test methods and value ranges are much more diverse than when published so typical values have become less relevant to today's industry.

Значение и использование

In establishing guidelines for specifying a membrane switch, it is important to allow application design engineers to base their decisions on requirements using known reasonable, achievable performance levels.

Over-specification increases cost and complexity; under-specification risks not meeting performance criteria.

Область применения

1.1 This guide contains a list of the current test methods and practices generated by Subcommittee F01.18 on Membrane Switches along with typical values for specifying certain performance characteristics of a membrane switch.

1.2 As a minimum, for any particular membrane switch, the values for the required characteristics should be specified.

1.3 Additional performance characteristics may be required and should be specified accordingly.
