In a vehicle battery relay assembly for disconnecting or isolating a vehicle battery from a connection line, a housing is provided having a solenoid and a switch activated by the solenoid. The switch electrically connects and disconnects a first contact terminal for connection to the vehicle battery and a second contact terminal for connection to the connection line. The solenoid has a solenoid coil. A rotatable ratchet gear rotates by engagement with a pawl, the pawl being connected to a plunger of the solenoid. The switch comprises a contact element coupled to the ratchet gear, the contact element having at least first and second projecting contact points. The contact element is positioned relative to a contact surface of the first and second contact terminals such that given a first rotation of the contact element the first and second contact terminals are electrically connected and given a subsequent second rotation the first and second contact terminals are electrically disconnected.
