Each button will generally operate the same way. There are a few components to each.
- Plastic Dome Piece and flange
- LED/LED housing
- Microswitch with 2-4 prongs
- Wires attached to each prong
Typically either the microswitch (the red/black piece) can lose its' ability to receive a switch or "click." Usually this happens from wear and tear of repeated impact.
Other times, it can be the LED that eventually stops producing light. The only way to access this is by twisting the entire microswitch and its' housing counter clockwise.
To Replace the LED
- Access behind the button (this is done differently depending on where the button functions).
- Identify where the microswitch and white housing are sitting.
- Spin counter clockwise to remove the white piece from the black cylinder.
- Remove the LED and its' first layer of housing to replace it with a fresh one
- NOTE - Take notice of which side is double wrapped with conduit. This edge will go into the POSITIVE (usually red wired/red colored) side.
- After inserted, insert into the matching slots in the black cylinder and turn clockwise.
- Your button should now have a fully functioning LED.
To Replace a MicroSwitch
- Follow very similar steps to the LED, but once the module is removed from the plastic button, you'll then remove the black/red piece from the white housing.
- To remove the microswitch, you'll need to remove all the metal prongs to the wires first.
- Once wires are off, peel the long white plastic knob out of the switch and spin it out.
- Wire up the new microswitch (2 or 4 prongs) and put back into white housing.
Insert the switch into the black cylinder.
Rotate the switch clockwise until the black knob lines up directly with the white push-down mechanism attached to the button.
- Reattach switch to the button and you should be done.
