The invention relates to a switching device adapted for use in instruments of personal defence to actuate two or more electrically or mechanically operated components of which at least one is electrically operated and at least one is mechanically operated. The device may be adapted for use in conjunction with the push button system of a torch, the push button system being operable both partially so as to actuate only the circuit for a bulb, and fully so as to actuate also a noise alarm device and mechanically actuate means capable of emitting a spray jet.
