Standard Test Method for Determining the Sensitivity (Teasing) of a Tactile Membrane Switch (Withdrawn 2008)

Scope

1.1 This test method establishes procedures for depressing and releasing a tactile membrane switch to determine the amount of switch teasing, if any.

1.2 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

The tendency of a switch to make or break electrical contact at unexpected moments during closure or release can be a sign of a poor design. The degree of teasing can range from a simple annoyance to a failure of critical control process.

The amount of switch sensitivity or teasing can also be a result of poor surface conductivity that will prevent an electrical event even when switch poles are in partial contact.
