Boramig selector switch

[M3_daz]

Good afternoon everyone

I have a Boramig which was working on power setting 1, 2, 3, 5 and 6 but not on 4.
Due to currently welding under the car, I took it upon my self to investigate as to why its not working.... what a massive mistake. well... I have found that the power selector switch (old bakelite) is broken, bridging link melted and contactors have arked out.

I was wondering if anyone on here has the part number or suggestion as to when I can obtain a new switch??

TIA

Try searching '6 stage rotary switch'.

Maybe '6 pole rotary switch'.

Kraus & Naimer here are good. I'd see if the CAD11 body style fits as it's beefier than the C4-1 type.

They're on 01635 262626, in Reading. Simon Horlock is their technical sales engineer that I've dealt with a few times. Can't quite see in your photos but the "K" makes me think it might be one of theirs.

Surprisingly not that expensive either.

Sometimes those switches do more than switch say 1 and 2 then 1 and 3 and so on, with 1 as the common. It can do say 1, 2 and 5 in position 1. Hexadecimal is it?

Boramig

Hi everyone, Ive recently acquired a Boramig 160. Im not familiar with the make, but it seems to be nicely engineered. However when fired up all I get is the cooling fan, nothing happens when I pull the trigger. In between rain showers im in the process of examining the wiring. Ive noted that...

the power selector switch is 1 pole 6 way.
There should be 7 connections to the switch. One is the Neutral power feed. The other six go to the transformer. One of those will be a single solid copper wire. It is the highest resistance of the primary winding, corresponding to the greatest number of turns and the lowest power setting ( number 1 ). The other five are tappings which come from and return to the primary winding, so there will be two solid wires under each terminal screw.

Pardon our interruption...

This s/h one is probably just about good enough to do the job:

This switch is six way and has a spring loaded roller detent with very positive locking.

I think this one is eight single-pole on/off switches. You would have to link 6 of the "rear" tabs together to act as the 1 pole ( so it would become 1-pole 6-way ), then block off or ignore the 2 extra positions:
