4. ALTERNATE LENS CHANGING
The pushbutton is factory shipped with the green lens set installed and two lens/insert options.
Changing to the other lens sets is simple.
1) Grasp keyplate and turn over. From the back rotate the white contact block of the switch
counter-clockwise to the 11 o’clock position and pull straight back to remove the contact
block.
2) With a slender smooth ended object such as a marker pen, slide it inside the switch body.
With the object inserted in the switch up against the lens, place the object on a smooth
surface with the keyplate on top, and tap the keyplate up and down on the object to pop
the lens off. Remove the lens and insert.
3) Turn the keyplate over and place the new insert onto front of switch, confirm that the text
on the insert is correct reading to the keyplate and place the matching colour lens on top of
the insert and compress around all edges of the lens until it snaps in place. Depress lens
several more times to ensure smooth operation and that the lens is not binding.
4) With the terminals upward insert the contact block back into the back of the switch at the 11 o’clock
position and rotate clockwise until it stops straight up and down.
