The plate is cut from .093 thick Delrin, and the text is etched into the surface. If you would like to enhance its readability, you can flood or fill the text with correction fluid (“white-out” or white paint) and then simply wipe off the excess. The fluid remains in the recessed etched lettering.

Both switches are exactly the same; therefore each can be put into either mounting hole. However, note that each switch has a bronze colored terminal (shown below) at one end (the other two terminals are silver). 

• Orient the switches such that their bronze terminals are closest to the “top edge” of the plate that has the “I” (on indicator). The orientation of the switch in the mounting hole is very important; double-check your installation.  Do not install these switches in reverse.
