This switch for controlling electric (power) windows, aerials and central locking motors is sometimes referred to as a polarity reversing 5-pin rocker switch. It works by swapping the polarity of the 2 pins to the motor and so reversing it's direction to make the window/aerial/door locks go up or down. The switch has a momentary action for each direction so returns to the centre position when released. See above pictures or click download link below for full explanation and wiring diagram. 

Useful as an emergency central locking switch.

The switch body is plastic and the rocker has a metal surround. It requires a 37 x 18mm panel cut-out and is retained via sprung 'arms'. 

Sold individually.
