(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.

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.

Interlock
For mechanically interlocking two push buttons so that only one
button can be depressed at a time. A K3 attachment is
furnished with the 9001KR11 and KR12 operators. However,
these are maintained operators and the K3 interlock serves to
release one of the buttons when the other is depressed. When
used with momentary contact buttons, the K3 interlock does not hold the buttons in the depressed position. It simply
prevents pushing both buttons at the same time.
The K3 interlock is mounted behind the operators. Operators
not included.

Interlock
For mechanically interlocking two push buttons so that only one
button can be depressed at a time. A K3 attachment is
furnished with the 9001SKR11,SKR12, SKRU1 and SKRU11
operators. However, these are maintained operators and the
K3 interlock serves to release one of the buttons when the
other is depressed. When used with momentary contact
buttons, the K3 interlock does not hold the buttons in the
depressed position. It simply prevents pushing both buttons at
the same time.
The K3 interlock is mounted behind the operators. Operators
not included.
