PUSH BUTTONS AND OPERATOR
INTERFACE
[82] When ordering, add prefix 9001 to the catalog number.
[83] These operators can be ordered complete with contact blocks. For maximum block usage, see “H” Codes, page 19-93. Add the “H” number to the end of the operator type number.
[84] ■ Add the voltage assembly code as chosen from Standard and Shallow Depth Light Modules, page 19-91. EXAMPLE: SK2L_ with 240 Vac/Vdc = SK2L25.
[85] On neon light modules, use clear color caps only.
[86] Add the color code as chosen from the color cap table below. EXAMPLE: SK2L25 with a blue 1-3/8 in. mushroom button = SK2L25L20.
[87] The cap must be the same color as the LED light module chosen, e.g., for green LED, use green color cap.
[88] The only difference between a no guard (SK2L) operator and mushroom button operator is the color cap.
