Front Axle Engagement Air Pressure Switch - Replacement

[frank8003]

The electrical pressure switch does unscrew from the valve assembly. The switch looks almost exactly like the brake light switch, once it is removed from the valve assembly. I took your photo, and added some text and arrow to point out the pressure switch.

The actual pressure switch with silvered contacts sealed is made by FASCO #1702-0990.
It is part 16 in WP 0042-001 in TM 9-2320-361-24P

You just use the same switch as the hydraulic brake switch on the master cylinder. Screws right in with no adapters and the original plug fits. Had mine in for over a year now.
