It's called a solenoid, and you can probably find one at your local

The other option is a linear actuator - which personally I prefer over
solenoids.
You should easily find something with googling ardiuno linear actuator
(Lot more out there for the Arduino just because it's been around so long -
same ideas/concerns apply).
Watch your current draw even with a
magnetic solenoid and a return spring

Is it a momentary switch? If so wire it in parallel. Either button or RPi

I agree with your approach: prototype the button-pusher with a solenoid to
ensure your idea works *before* you tear apart the working hardware -- a normal
engineering approach.
Be sure to use a diode across the solenoid coil as was suggested elsewhere. If
you're unsure of a circuit, I'm sure

also have tutorials that'll help.
Amazon also has lots of stuff if you already kinda know what you want. If you
