Garage door button

I need to install a manual switch for a motor on a garage door. Can telephone 24awg be used for this - what is the norm?
Bell wire solid copper?

If your using 2-pair phone wire I'd twin the wires. 18 gauge 2-conductir thermostat wire would be another choice.

What do you mean by twin? Just twist the ends together or twist the whole length of wire?

Will any door bell push button from the hardware store do the same job?

Assuming standard 2-pair phone wire twist the green and red together on a both ends and twist the black and yellow together on both ends. Use red green for one wire and yellow black for the other. (Wire colors chosen for convenience of explanation. Any two wires can be joined to form a single wire.

Only ones with no light.

No but under perfect conditions it could halve the current on each wire. You might want to read this: Increasing wire gauge by twisting pairs - Electrical Engineering Stack Exchange
