A tamper switch arrangement detects tampering with a device, and includes a tamper switch assembly having a tamper switch with a first part and a second part. The first and second parts are movable relative to each other between an open switch position and a closed switch position. The tamper switch is biased into one of the open and closed switch positions. An enclosure substantially encloses the tamper switch assembly and the device. The enclosure includes a door and an opening disposed opposite the door. The enclosure is sized such that the tamper switch assembly may be compressed between an inner surface of the door and a second surface via the opening to thereby overcome the bias and actuate the tamper switch into an other of the open and closed switch positions.
