ignition switch

I have an’82 Fiberform with a Volvo Penta 260A. The ignition switch is shot. It is a three position (off, on, start) six spade: 2 magnetos (empty) 1 Battery, 1 Solenoid, and a dual post Accessory that the Choke and the Accessory is on. It is NOT a push-to-choke. Will Part# 239032 Mfr#MP39770 replace it?

ingition switch

Looking for a =n igition swich to use on a custom motorcycle. Do you need a relay on this unit?


Response - There are few modern switches that will pass current directly from the battery to the starter itself. However, this switch will work fine on a modern bike - you are passing power to the solenoid whech opens power to the starter.
