Microswitch

Modified on Wed, 23 Mar, 2022 at 10:11 AM

Tools Required: Phillip's head screwdriver, pliers (optional).


  • With the battery taken out of your sprayer, take your screwdriver, unscrew the cover plate, loosen the strain relief fitting, and set aside.
  • Locate the microswitch housing (it looks like the letter "P") at the bottom of the pump. Remove the top and bottom screws from the housing to reveal the microswitch.
  • Take the microswitch out of the pump. Using pliers, gently disconnect the spade connectors from the old microswitch. Make sure to remove using the retaining tabs and not by pulling on the wire. Reattach the connectors to the replacement microswitch.
  • Place the replacement microswitch  into its slot and secure the screws back onto the housing.
  • Insert a battery into the battery holster and turn your sprayer on. Test the sprayer. If the sprayer is functional, close it up and secure the cover plate.
