INSTALLATION OF CONTACT BLOCK
(Catalog Number ESWP126)
Install the required number of contact blocks to the mounting
block or mounting plate.
The field wiring terminals on the contact block are marked.
The , and "O" indicates normally open contacts; and
and "C" indicates normally closed contacts of the contact block.
The lugs on the contact block are provided with binding head
screw terminals.
• Strip the insulation on each conductor wire back 3/8".
• Use a slotted or Phillips head screwdriver to loosen the field
wiring terminal screws the required 3 or 4 turns.
• Insert the bare wire conductor(s) on either side of the terminal
screw(s), under the terminal clamp(s) and securely tighten the
screw(s).
Note: Do Not exceed 15 in. lbs. of torque.

ASSEMBLY OF PILOT LIGHTS
(INCLUDING TRANSFORMERS)
Select the DL legend plates with proper markings or marking
windows. Orient them horizontally on the cover as desired. Note a
marking window is provided for field marking customer's specific
terms. Assemble the pilot light assembly through the legend plate
and onto the cover. Tighten the pilot light assembly to the cover
until it bottoms out on the thread. Use the ¾ - 20 lock nut on the
inside of the cover to secure the pilot light to the cover. See
Figure 9.
If using a transformer do NOT use the ¾ - 20 lock nut. Fasten the
mounting block to the pilot light assembly from the inside of the
cover. Orient the mounting block so that the transformer does not
interfere with an adjoining device, as shown in Figure 2. Tighten
the set-screw thereby locking the pushbutton assembly to the
cover, see Figure 9. Mount the transformer to the mounting block
using the mounting screw and lock washer. Connect both wire
leads of the pilot light to the secondary side of the transformer
using its white wires. Safely insulate each of these connections by
use of wire nuts. The primary side of the transformer (black wires)
is to be connected to the power supply. See Figure 10 for wiring
diagram of pilot light.
Note that one of the holes in the mounting block is tapped to
accept the mounting screw. With the lock washer on the
mounting screw, insert mounting screw first into untapped hole.
Test wiring for correctness with continuity checks and also for
unwanted grounds with an insulation resistance tester.
Carefully assemble cover assembly to the back box with the cover
screws. Check the tightness of the cover screws to ensure that
the cover assembly is securely fastened.

• Referring to Figure 11, install bearing / shaft sub-assembly to
the front side of the cover by threading it down tight to the
cover in the desired location. Use a DL legend plate if required
as noted in ASSEMBLY OF PUSHBUTTONS.
• This step will allow the contact block(s) to be in the proper
position. Fasten the mounting block to the bearing / shaft sub
assembly on the inside of the cover. Tighten the setscrew
using a 1/16" Allen wrench thereby locking the mounting block
to the cover. Orient the mounting plate on cam module
assembly so that the two flat sides are parallel with the long
side of the cover. Then, slide operator module assembly onto
shaft. Fasten the cam module assembly to the cover using #6-
32 lockwashers and screws.
• Assemble the necessary contact block(s) per instructions in
INSTALLATION OF CONTACT BLOCK section.
• Orient the knob / lock tab assembly so that the indicating mark
points to the desired position for full travel for both 2 and 3
position selector switches. Tighten #4-40 screw to fasten knob
/ lock tab assembly in this proper position.
• Referring to Figure 12, test wiring for correctness with
continuity checks and also for unwanted grounds with an
insulation resistance tester.
• Carefully assemble cover assembly to the device body with the
cover screws. Check the tightness of the cover screws to
ensure that the cover assembly is securely fastened.

• Referring to Figure 13, install bearing / shaft sub-assembly and
spring washer to the front side of the cover by threading it
down snug to the cover in the desired location. Use a DL
legend plate if required as noted in ASSEMBLY OF
PUSHBUTTONS.
• This step will allow the contact block(s) to be in the proper
position. Temporarily mount the cam module assembly on the
shaft and loosely fasten to inside of cover using #6-32
lockwashers and screws. Back out the bearing/shaft
subassembly until key is removable in proper position(s). Install
locking collar tight against cover, check key removal and adjust
bearing/shaft subassembly if necessary. Remove cam module
