Switch for BP800

[Harrison123]

The switch for my Volvo Penta QL BP800 bow thruster is bad. I need a replacement for it. The Volvo Penta part number for this is 41100743 but it does not look like they make it anymore. See page 5 on the attached document. Does anyone know who might have it or if there is something else I can use as a replacement. I was at a boat show and I was told the switch was odd and I needed to be careful. I guess if I could be the spec's on it I could build it from scratch.

Look at the switch and see if you can determine the amp rating of the switch. Then look up Exp: 15 amp joystick switch replacement

It will come back with things like these

Note the higher the amp rating the heavier the switch. If you only need 10 amp its all good to use a 15 or 20 amp switch.

Now that said, you could change it to a double pole double throw with off in the middle toggle NC-OFF-NC

here is a simple toggle switch that would fit the bill

Still working on this. I did manage to find a schematic of the switch with part numbers. I may have to do an old fashion "rebuild" of the switch. See below link on page 56-57.

Thanks for the link. I found the switch on eBay last night for $18 so I bought it. The thruster is more of a left/right switch. I would love to replace it with more of a joystick type of switch. Just easier to handle when docking, but at least I have something to go on for now

since its a single pole switch, it is a pilot switch that is switching a reversing contactor.
