Just replaced the low air pressure switch on an M813 and it looks exactly the same.

yes,it activates the low air pressure warning buzzer. i put a screw in mine, some other guys have also. put some sealer on the threads too.

Most compressed air systems come with small bleed holes to discharge any condensate build up. If the water is not allowed out then corrosion soon causes things to stop working. Maybe it leaks by design.
