Abstract
The fail safe system has a pushbutton (A) which when actuated acts through bellows (B) and conduit (C) in the supply cable to increase the pressure in the second bellows (E) in the supply plug. This causes the contacts to close in the plug so that mains electricity is supplied to the appliance. The obtained air movements and pressure variations are pushed through a small connecting pipe.
