ABSTRACT:
A module for controlling power supply to a load in a product which includes a microchip, and an electromechanical switch and a proximity/touch sensor connected to the microchip, preferably to the same input. The switch is primarily used to activate or deactivate the load and the proximity/touch sensor to vary the effect of operating the switch, or to control additional functions such as the activation of a signal, typically a light signal, which helps to locate the product, particularly in the dark, and to vary the duration of an automatic time-out period at the end of which the load is deactivated.
