Claim 20:
21. The apparatus of claim 1, wherein the circuitry includes a printed circuit board on the first portion, a first switch having ON and OFF conditions; a second switch having an extended position and a retracted position, the extended position reaching farther outwards from the printed circuit board than the retracted position sufficient to detect removal of the second portion from the first portion; and a third switch operable by receipt of broadcast of energy; wherein:
the circuitry is configured to unite cooperation of the first switch, the second switch, the third switch, and the alarm, such that: the circuitry is in the armed state when the first switch is ON and the second switch is in the retracted position, and the alarm is triggered as an undisarmed breach of the armed state when the circuitry detects an electrical change during the armed state, and the circuitry is disarmed by the receipt of the broadcast of energy by the third switch; and
the second portion includes a pin extending through the second portion and providing the second switch with a reach sufficient to detect removal of the second portion from a surface.
