Abstract
A tamper switch actuator is used in combination with a circuit board held between two outer structural members. The tamper switch actuator includes a suspended displacement member moveable to a conducting position after a given amount of compression of a compressing member. The compressing member cooperates with an outer protecting sleeve and is positioned within and moveable in the axial direction of the sleeve. The tamper switch actuator separates the outer protecting sleeve from the displacement member. With this arrangement the electrical conducting surface of the displacement member can quickly respond to separation of the casing to produce a non-conducting condition or tamper indicating conditions while remaining protected within the outer protecting sleeve.
