Tools and Materials Needed
- Solinst 12V Compressor On/Off Switch (Set of 10) (#111839)
- 1/4" Inner Melt Heat Shrink
- 3/8" Wrench
- 5/32" Allen Key
- Wire Cutters and Strippers
- Solder and Wire
- Heat Gun
(comes with set of 10)
1/4" Heat Shrink
(cut into two 1" pieces)
Ensure the power supply is disconnected from the 12V Compressor and the pressure has been fully vented from the tank.
- Pull to remove the leads from the motor assembly. Remove the air line from the fitting on the motor assembly.
- Use the 3/8" wrench to stabilize the nuts, while using the 5/32" Allen key to undo the bolts holding the motor assembly to the Compressor frame.
- Remove the motor assembly from the Compressor frame. Note, the motor will still be connected to the Compressor by a black ground wire.
- Disconnect lead that connects the 12V compressor on/off switch to the fuse.
- Use the pliers to undo the nut holding the on/off switch in place, and remove the switch from the Compressor frame.
You will re-use the "ON/OFF" metal label from the old switch.
- Cut the leads off the old on/off switch as close to the switch as possible. Remove the old heat shrink and strip the ends of the leads. Slide a 1" piece of heat shrink onto each lead.
- Solder the leads to the new on/off switch. The white lead goes to the middle terminal, and the red lead to the other.
- Slide the pieces of heat shrink over the soldered connections and shrink in place using the heat gun.
- Ensure the hex nut is screwed 1/3 of the way onto the new switch. Place the switch through the opening in the compressor frame, ensuring the terminal with the red lead is to the right.
- Place the metal on/off label over the new on/off switch, ensuring the side labeled "ON" is next to the fuse. Secure the switch using the nut.
- Reconnect the lead from the on/off switch to the fuse.
- Use the bolts to mount the motor assembly back onto the Compressor frame.
- Reconnect the leads to the motor assembly. The lead from the on/off switch goes to the closest/inside connection.
- Reconnect the air line to the motor assembly.
