12 Volt Compressor Pressure Switch Replacement

(Page 1 of 2)

Tools and Materials Needed

1. Pressure Switch for the 12V Compressor (Spare) (#113545)

2. Two Adjustable Wrenches

Instructions

CAUTION: Ensure the power supply is disconnected from the

12V Compressor and the pressure has been fully vented

from the tank.

1. Pull to remove the two leads from the old pressure switch

on the 12V Compressor.

2. Use the two wrenches to unscrew and remove the

old pressure switch from the brass ﬁtting on the 12V

Compressor. Use one wrench to stabilize the brass ﬁtting,

and the other to unscrew the pressure switch (see below).

3. Remove the two covers from the connections on the new

pressure switch.

4. Screw the new pressure switch into the brass ﬁtting and

tighten using the two wrenches.

5. Connect the two leads to the new pressure switch (this

switch has no polarity, so it does not matter which lead is

connected to which terminal).
