Miller Edge AW 14 Air Wave Switch Housed in ABS Box
The Miller Edge AW14 is an Air-Wave pressure switch in an ABS box. It is used with Air-Wave configured sensing edges and treadles where an enclosed switch is needed but a NEMA 4 polycarbonate AW12A enclosure is not required. The AW14 is also commonly seen with Air-Wave kit configurations using gum rubber hose, end plugs, barbed connectors, and mounting hardware. It converts a pressure wave from the edge hose into a switch signal for the motor control circuit.
Common Applications and Replacement Reasons
- Used when an Air-Wave edge switch is damaged, out of adjustment, contaminated, or no longer responding consistently
- Used for air-activated sensing edges and treadles on motorized doors and select gate systems
- Often serviced along with air hose, end plugs, barbed connectors, and coil cord parts

Technician Note
These Miller Edge Air-Wave switches are non-monitored pneumatic pressure switches. They are useful in cold, wet, refrigerated, high vibration, and condensation-prone locations, but they are not a substitute for a monitored edge where the operator requires monitored entrapment protection.
Before Ordering Checklist
- Confirm the original system is Air-Wave configured, not electric or resistive edge wiring
- Confirm the operator input can accept the selected non-monitored switch output
- Match the enclosure style to the environment and mounting location
- Inspect air hose, plugs, tubing, and fittings for leaks before replacing only the switch
- Cycle-test the edge after installation and confirm the operator stops or reverses properly
Professional Advisory
Do not use a non-monitored Air-Wave switch to bypass a required monitored safety device. For newer gate and door operators or unclear safety inputs, have a qualified technician review the operator manual, UL 325 requirements, and the full entrapment protection layout.
Product Questions and Answers
What is the Miller Edge AW14 used with?
The AW14 is used with Air-Wave configured sensing edges and treadles, including many AW14K500 air hose kit layouts.
Is AW14 the same as AW12A?
No. Both are Air-Wave switches, but AW14 is housed in an ABS enclosure while AW12A uses a NEMA 4 polycarbonate enclosure.
Is AW14 a monitored edge switch?
No. AW14 is non-monitored and should not be used where the operator requires monitored external entrapment protection.
What edge length is supported by this Air-Wave switch family?
Miller Edge lists the AW10, AW12A, and AW14 Air-Wave switch family for Air-Wave configured sensing edges up to 60 ft.
What parts are commonly checked with an AW14?
Check the gum rubber hose, end plugs, 218-27-18 connector, coil cord if used, and the operator input before replacing the switch.
