Installation Instructions for the
MICRO SWITCH GLL Series Limit Switch
mWARNING
PERSONAL INJURY
• Where possible, install these switches with the conduit
opening pointed down to drain moisture away from switch.
• Do not install switch at the low point of a conduit run.
• Install a fitting into the conduit opening that provides
strain relief to the wires/cable, as well as sealing against
contaminants found in the application.
• In applications where fluids or moisture may be present,
seal the fitting threads with a product such as Teflon tape
or pipe dope.
Failure to comply with these instructions could result in
death or serious injury.
GENERAL INFORMATION
1. Refer to page 2 for specifications.
2. Rotate switch head to desired position (90° increments).
Review adjusting instructions below.
3. Mount switch using two M4 or #8 screws (not included).
Torque screws to mounting surface 4,9 N m to 5,9 N m
[43.4 in lb to 52.2 in lb].
4. All normally closed (NC) contacts are direct opening .
POSITIONING LEVER
The lever on rotary actuated units is adjustable to any of the
segmented positions 360° around the shaft; however, the
degree of rotation is dependant on head position and direction
of roller.
1. Loosen the lever retaining screw with a Phillips head
screwdriver.
2. Remove lever.
3. Reposition lever to desired location.
4. Securely tighten screw.
REVERSING THE ROLLER LEVER
The roller arm may be reversed to face the roller to the inside or
outside of the arm.
ADJUSTABLE LENGTH LEVERS
1. Loosen the lever’s adjustment screw using a Phillips head
screwdriver.
2. Adjust to desired length.
3. Securely tighten adjustment screw to 1.0 N m [8.85 in lb] of
torque.

ADJUSTMENT INSTRUCTIONS
To give flexibility in application, the user can perform the
adjustments described below in any order before wiring the
unit.
ACTUATOR HEAD POSITIONING
The actuator head may be positioned in any of four directions.
1. Remove the four head retaining screws while holding
actuator head in place.
2. To prevent actuator spring loss, remove head slowly to
relieve spring tension prior to removal.
3. Rotate actuator head to desired position.
4. Position the large diameter end of the actuator spring
over the actuator. Place retaining screws through gasket
material and position head over screw holes in desired
position.
5. Securely tighten the screws to 0,2 N m [1.7 in lb] of torque.

TOP ROLLER PLUNGER
Switches with top roller plunger must be mounted with plunger
in desired position. Actuating device must not exceed over
travel distance.
WIRING
1. Remove front cover plate screw.
2. Contact block area by terminal screw is labeled for NO
(Normally Open) and NC (Normally Closed) contacts.
3. Connect stranded wire (0,75 mm² - 2,5 mm², 18 AWG14
AWG) or solid wire (0,75 mm² - 1,5 mm², 18 AWG16 AWG)
to desired connector terminals. Use 90 °C [194 °F] rated
wire when ambient temperature is to exceed 75 °C [158 °F]:
• Torque switch terminal screws to 0,8 N m to 1,0 N m
[7.1 in lb to 8.9 in lb]
4. Securely tighten cover screw to 0,5 N m [4.4 in lb] of torque.
