ASTM-F1661 › Standard Test Method for Determining the Contact Bounce Time of a Membrane Switch (Withdrawn 2024)
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method covers the determination of the contact bounce time of a membrane switch.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
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
4.1 Contact bounce time is essential to manufacturers and users when designing interface circuitry because it specifies the time delay necessary in the decoder circuitry to avoid any false signals caused by contact bounce. Allowing for time delay makes the switch operation considerably more reliable.
