ASKING FOR HELP FROM AN ELECTRICIAN/ENGINEER SOLDERING A MICROSWITCH WHICH WIRE GOES WHERE

[Tedpetal18]

Hi all
I have a mobility scooter which suddenly stopped working. The soldering from one of the wires in the brake micro switch had come away.
I have ordered a new 3A/250v micro switch which has 3 pins. I think I need to solder onto the 2 outer pins. What I need to know is which wires do I solder? Stupidly I walked away from it for a couple of days then totally forgot what wire went where! Please see photos attached. I’d be so grateful for any advice. I cannot get out very far without my wheels. Thanks, Emma xx
Oh, I have spread the wires to show them clearly if we say number 1 is the one I’m pointing to…to number 4 at the other end. Thanks again x

You titled this "

ELECTRICIAN ENGINEER SOLDERING A MICROSWITCH WHICH WIRE GOES WHERE​

I'm curius, where does the "electrician engineer" bit come into it?

Please also give some more information.
What is the motor make & model number? It should have a data plate on it or some markings.
What make/model scooter is it from?

What make/model is the microswitch? (They are usually common closest the lever, then N/O then N/C furthest from the lever.)

I am asking for help from an electrician/engineer, I hope that resolves your curiosity on that part.
The scooter is a sterling sapphire 2 I don’t know the year. I will add some more photo’s showing the brake model & micro switch number. I do hope you can help. It’s a 3A/250V 3 pin switch. Nothing goes in the middle pin, I need to know which wire goes into which end. Thanks so much

If you have obtained a similar switch and there are only 2 wires and you know which pin was not in use...
Then it should not matter which of the wires go to which of the 2 pins.

Are the new and the old switches marked with 'COM' 'NO' 'NC' ?
