It has been suggested here that the master switch referrred to would only be wanted in connection with a car fitted with an electric heater as such fittings as lights, cigar lighters, windscreen wipers, etc., are either obvious or intermittent. Possibly you intend to make this master switch safeguard the ignition circuit also instead of introducing the red warning light/the switch is 'on' with the engine stationary. when Cx.{Major Len W.
