A battery isolator switch has main battery contacts and an auxiliary contact for controlling the supply of excitation current to an alternator. In order to ensure that there is a delay between opening the auxiliary contact and the main contacts when the switch is tripped by a remote contact, there is provided a latching circuit which energizes a relay for opening the auxiliary contact, and a delay circuit for turning on a transistor after a suitable delay, to energize a main tripping winding via another relay.
