The Miller Edge AW14 garage door opener air wave switch works on doors up to 60 feet in length. After being compressed through a hose or extrusion, the switch activates when a wave of air acts upon the diaphragm. This contact converts the positive or negative pressure wave respectively into an electrical contact. Because the over-pressure escapes through a valve opening, the contact is of short duration. That makes this Miller Edge air wave switch from North Shore Commercial Door ideal for normally-open or normally-closed garage door operations.
