During a crazyflie dogfight, a prop of the other quadcopter hit my quad in an unfortunate way, completely breaking off the tiny on/off switch. Now I can't switch the quad on anymore

I might be able to with a small pin or something, but I haven't found one yet.
Any advise for a more permanent solution? Is there maybe a way to replace the little moving part of the button? Or perhaps remove the complete switch and solder a new one on it?
