(1) These operators can be ordered complete with contact blocks. For maximum block usage, see page 22. Add the “H”

number chosen from page 22 to the end of the operator reference number and add the cost of the “H” number to the operator cost.

(2) Replace b with the voltage assembly code as chosen from the tables on page 24. Example: K2Lb with 240 Vac/Vdc = K2L25
(3) On neon light modules, use clear color caps only.
(4) The cap must be the same color as the LED light module chosen, e.g., for red LED, use red color cap.
(5) Replace e with the color code as chosen from the color cap table below. Example: K2L25e with a blue 13⁄8 mushroom button = K2L25L20
(6) The only difference between a no guard (K2L) operator and mushroom button operator is the color cap.

This module can be added to standard 9001K,
9001KX, 9001SK or 9001T momentary push
button operators. Contact blocks mounted

behind this module (maximum of 2) are held in

the depressed position when the operator is
pressed once, and released to their normal
position when the operator is pressed again.
For a N.C. circuit, use a 9001KA3 or the N.C.
contact of either a 9001KA1 or 9001KA4. For a
N.O. circuit, use the N.O. contact of either a
9001KA4 or 9001KA6.
