Exactly the info I needed to bypass a failed truck window switch. thanks

[@MikaelAbehsera]

Glad it helped

[@BillRen-nl5mx]

Clearest explantion on RUclips thank you very much

[@MikaelAbehsera]

Thanks Bill

[@cristhianc.3519]

This been bugging my brain for a time, I was thinking how to do the same thing for a rotary switch. Thank you!

[@MikaelAbehsera]

Glad I could help!

[@jessejames041]

You explain the motor positions go on the top two pins, but your picture shows the motor in the middle pin positions?

[@crossbarranchin7728]

good job explaining it thanks

[@MikaelAbehsera]

Glad it helped

So why do these switches come with prongs?

[@dakotak8437]

I have an old hofmann brake lathe i wanna make the one motor forward reverse switch. But the swith on it now has 4 tires and the motor has 3 but go into 2 separate power boxes. Idk if you can help or not

[@MikaelAbehsera]

Hmm sounds weird, I’m not sure how it works with a lathe since you do need to control speed but couldn’t you control the direction in the same way I did then direct that power into the speed controller?

[@dakotak8437]

@@MikaelAbehsera is one of those on off switches that has 4 wires going to it and it's just to move the cutter no speed control

[@quietudinal4857]

Does this work for a brushless fan power cable? Can't understand why your method did not work for this application.

[@MikaelAbehsera]

it should? if it has positive and negative, and those can be reversed (dc motors usually) then I dont see why not

[@anonymousguy7251]

Will this work for bldc motor?
Is there any way to switch the polarity, dynamically via code.

[@MikaelAbehsera]

it should yes, dynamic control via code requires an Hbridge module, I forget the other name for it but they do exist and arent crazy expensive

[@jerrythompson2608]

Would this work for a power window application in a vehicle?

[@cristhianc.3519]

Yes it should work for any DC motor

[@MikaelAbehsera]

it shoudl yeah!, just make sure the switch can handle the power going through it
