Abstract
A Tamper Switch Assembly to protect cryptographic modules and electronic components within a closeable unit. The Tamper Switch Assembly includes a Lid Switch Actuator affixable to an underside of a lid of the closeable unit, and a Lid Switch Guard Bracket affixable within a chassis of the closeable unit. The Tamper Switch Assembly includes an Electronic Switch Assembly insertable within the Lid Switch Guard Bracket to provide electrical monitoring of a switch state. A microprocessor is coupled to the Electronic Switch Assembly by communication means to monitor the switch for electrical continuity to determine its state, and in response, determine whether a tampering of the securely closed unit has occurred. Other embodiments are disclosed.
