Abstract

SWITCHING DEVICE A system for controlling the activation of an electrical load comprising a receiving device for receiving an ambient condition input; a output device, in communication with said receiving device, arranged to output a signal proportional to the ambient condition input; a controller for receiving the signal from said output device and comparing said signal to a reference value; said controller arranged to deactivate a switch in communication with said electrical load on detecting the signal exceeding the reference value and activating the switch when the signal falls below said reference value.
