Erbauer impact driver repair

[RaceDiagnostics]

Does anyone know where I can get a replacement switch, this one has become intermittent.

There is writing on the switch above the 01203Q. Can you show it so it is legible?

Does eBay have any spare or repair models?

Is it 100% the switch and not bad contact with the battery? If you squeeze and it does not work, the instinct is to shake it, and that might make a dodgy battery contact re-connect?

Theres 7 wires going to the switch which tells me it is not a simple on off, or variable resistor type. It will have a load of resistors and pcb traces for the switch to wipe, giving the impression of variable speed, but really its speed steps.
Quite simple inside, a few springs, I have had a few apart before and can be cleaned up.

Found one on eBay.

1pc Trigger Switch TN28 20.1A 28VDC 20.1A 42VDC

I'll try and open up for a look but if not I'll probably just buy another bare unit and keep this for spares. Too much hassle getting one from the US. Refurbished ones on eBay are about £25.

I have a brushless impact erbauer that's not working but the switch may be ok.
Not sure if it's the same switch but I'll have a look if you are interested.

I'm going to be away from home for the next 10 days and will check out the existing one when I get back. Thanks for the offer, I'll let you know then if I can't get mine to work.
