Abstract: A starter relay includes a battery terminal, a starter motor terminal connected to the starter motor and a coil for making the relay contacts, with a coil terminal and an energizing circuit which includes a safety switch, as well as an ignition switch and starter switch. Two manually-operable bridging contacts are provided for making connection between the battery terminals and starter motor and respective leads which are connected to the two sides of the safety switch so that manual starting requires closing of the safety switch, as well as the closing of both bridging contacts. The bridging contacts are preferably contacts secured inside an insulation housing which prevents access to the battery and coil terminals for bridging from the outside. Pressure on the housing pushes the bridging contacts into contact with their respective relay terminals.
