Can anyone tell me what the voltage requirements are for a switch that
will be used to replace an existing inside the house garage door opener
manual switch?

I have purchased a replacement, and I understand that the line coming
from the garage door opener is basically a low voltage unit. I've
purchased what is a door bell ringer switch, but it's rated at up to 16
volts. Will this work for what I want to do?

The Garage Door opener is a Sears Craftsman/Chamberlain unit.

Thanks,

Danny
