Abstract

Apparatus (7) for switching a filament lamp (2) in a load circuit (1) by short circuiting the load switch (3) of the load circuit (1) comprises a relay (RL1) with contacts (9) to short circuit the switch (3). The apparatus (7) switches on the load circuit (1) in response to an infra-red detector (8) detecting the presence of an intruder within the perimeter of a compound or building. A power circuit (16) comprising a rechargable battery (B1) and storage capacitor (C3) powers the relay (RL1). The power circuit (16) derives its power from the load circuit (1) across the terminals of the switch (3), when the switch (3) is open and the relay contacts (9) are open. In this condition, a battery and storage capacitor in the power circuit (16) are charged.
