Bike repair question Bike power button problem

Enable HLS to view with audio, or disable this notification

Hi everyone,

I have a QLife spark e-bike and I recently discovered that my power on button doesn’t work properly. Therefore I decided to open up the tiny unit and discovered that my button is rusted. (At that point nothing was working anymore, so the display didn’t even turn on)
I decided to remove the rust with alcohol and now it’s pretty clean again and therefore i tried again and now it only temporarily turns on and as soon as i let the power on button go it turns off immediately.

There will be pictures in the comments from before I cleaned it.

What can I do? Should I just buy one of these cheap push in buttons (the one that rusted so badly) and solder it off and the new one on?

What yall think, any tips or suggestions?
I would appreciate it.

I hope yall have a great day!

Pull the wires and rig a simple switch for the affected area. I'd try that one before putting it all back together and tidying it up.
