Actuators for rotary switches such as

WLCA❑-TS roller lever and WLCL-TS rod

lever switches can be positioned within a

360° range. Loosen the Allen-head set bolt

on the side of the actuator, position the

actuator, then tighten in place.

Actuator lever

can be installed

at any angle in

360°.

■ ROTARY ACTUATOR POSITIONING

The operating head of many switches can

be set to four 90° positions to match

installation requirements. Loosen the four

Phillips head screws on the operating

head, and lift the head off. Then, position

with the shaft in the desired direction.

Replace the four screws to fasten the

operating head. Applicable switches

include those with roller levers (WLCA❑-

TS), rod levers (WLCL-TS), horizontal

plungers (WLSD❑-TS) and roller plungers

(WLD2-TS and WLD28-TS).

■ OPERATING HEAD POSITIONING

Example of roller lever, rod lever and

horizontal plunger switches

Head

Loosen the screws

Example of roller plunger switches

Rotary actuator switches can be set for

clockwise (CW), counterclockwise (CCW) or

operation both ways (CW+CCW). To change

the operating direction, loosen the four

screws on the switch head. Then, lift off the

head. The plunger marker inside is set

parallel with the face plate, as shown at right.

Turn the plunger so the marking faces left for

CW or right for CCW as shown. Replace the

actuator head in the direction suitable for the

installation and tighten the four screws.

The roller(s) on roller lever actuators may

be faced inward toward the operating head

or use the more typical installation with the

roller lever facing away from the body. To

change the actuator position, loosen the

Allen-head set bolt, pull the actuator off,

and reposition it on the shaft. Then, tighten

the set bolt at the desired angle.

■ STATUS INDICATOR EQUIPPED SWITCH OPERATION

WL switches are available with neon lamp

and troubleshooting. They come factory-

set for Normally Open operation ON. It is

easy to change the status to Normally

body, and rotate lamp holder 180°. Then,

replace the unit in the housing.

Switches with adjustable lever and rod

Overtravel Type

Standard Limit Switches Overtravel Limit Switches

Overtravel type limit switches offer a longer

overtravel (OT) to accommodate different

cam shapes. The key difference between

"standard" and "overtravel" is in the angle

of operation: overtravel types can operate

at 90° on either side of the center point.

Standard types are recommended for

operation at 45° on either side of the center

point. However, overtravel type switches

cannot be expected to provide 90°

operation on only one side.

Levers for WLCAL4-2-TS and WLCAL5-2-TS have a large tare, so positioning the actuator with the bottom up will reduce chattering.

Operating characteristics of WLCA12-2-TS are measured at arm length of 38 mm (1.29 in).

Operating characteristics of WLCL-2-TS are at arm length of 140 mm (5.51 in)

Operating characteristics of WLCAL4-2-TS are measured at rod length of 380 mm (1.25 ft)

Operating characteristics of WLCAL5-2-TS are measured at rod length of 412.5 mm (1.35 ft)

Legend: OF = Operating Force (max.); RF = Reset Force (min.); OT = Overtravel (min.); PT = Pretravel

MD = Movement Differential (max.); OP = Operating Position; TT = Total Travel (min.)

WLGCA2-TS Short Roller Lever High Precision Switch

The key differences between "high-

precision" and "standard" limit switches

are in the pretravel (PT) ratings and the

repeat accuracy. High-precision

switches have a pretravel (PT) of 5°

compared to 20° for standard switches.

The repeat accuracy is best compared by

referring to the graph at right. High-

precision switches are ideal for position-

ing control in machine tools and other

applications.
