We stock a variety of pneumatic and air wave switches and components.

Air Wave Switches

AW10 – Switch 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.
