This Switch has a max rating of 270vac is rated for 25amps and is usually found on 208-230vac motors

It has 2 male spade connectors sticking out of the side and bottom and has a small plastic button on the top of it which is what actuates the switch. There are 2 holes diagonally from each other in the corner of the switch for mounting into the housing. These are mounted in a switch housing which is what is actually pressed or pulled by the limit switch mechanism. These switch housing are many times green in color and are threaded for mounting in the motor housing or a housing on top of the lift.  This listing is for the switch only and unless your housing is damaged this will make your lift function again. We did picture the switch housing for reference purposes in pictures. The housing is not included in this listing but is available.
