The connection terminals on the back of these Request to Exit buttons seem to resemble what I can guess is a "compression lugs". Not really sure what they are called and I'm not familiar with general strategy to connect wires to these types of terminals.
Without knowing the precise size, what is the type of connector one would crimp to end of a wire to securely connect to these type of lugs?
