Doplňujúce informácie
| Significance and Use |
|
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. |
| 1. Scope |
|
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. |
