Standard Practice for Contact Closure Cycling of a Membrane Switch
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This practice covers the setup, procedure, and apparatus required to depress and release a membrane switch to a predetermined number of cycles.
1.2 This practice also covers the optional use of specified voltage and current during the cycling of the membrane switch.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Significance and Use
Contact closure cycling is useful to manufacturers and users for determining the effect of repeated closing of switch contacts or the effect of repeated flexure of other switch components.
The characteristic(s) are measured before cycling begins and then again after cycling ends.
