Miller Edge Air-Wave Switch Alarm, No Enclosure - AW10

The Miller Edge Air-Wave Switch Alarm operates on an air pressure wave which is led, via a hose or pipe, to a diaphragm contact. This contact converts the positive or negative pressure wave respectively into an electrical contact and pulse. The contact is of short duration, due to the fact that the overpressure escapes through a valve opening. No enclosure included
