MICRO SWITCH Maintained Cable Pull limit Switch
Step 2 -Attach cable to switch:
Ensure cable is fully seated and tightly fitted in
l
thimble groove.
Attach using two U-bolt clamps. U-bolt clamps
l
should be installed as close as possible to
thimble.
Tighten U-bolts to 4.5 in.-lb. (0,51 N-m) for 1/8 in.
l
(3,18 mm) cable and 7.5 in.-lb. (0,85 N-m) for
3/16 in. (4,76 mm) cable.
Step 3 - Install cable supports:
Install a cable support as close as practical to
l
end of shaft without interfering with switch
operation.
If cable tension adjusting turnbuckle is in mid-
l
span of cable, the first cable support should be in
line with, and no further than, 12 in. (30 cm) from
the end (eye) of the shaft. If adjusting turnbuckle
is attached directly to shaft eye, this distance
may be increased to 18 in. (46 cm).
Support cable at intervals no greater than 8 ft.
l
(2,4 m).

REQUIRED ENDSPRING AND TURNBUCKLE
INSTALLATION
Step 1 - Ensure you have the following
5 and 6):
Endspring, turnbuckle, jam nuts (supplied with
l
switch).
Thimbles, U-bolt clamps.
l
Step 2 - Install endspring:
ambient temperature fluctuations and provides a
measure of protection against excessive force
being applied to cable.
Install an endspring within cable span, preferably
l
at end of cable opposite switch (see Actuating
Cable Installation, Step 2).
Step 3 - Install turnbuckle:
tension.
IMPROPER INSTALLATION
Do NOT install turnbuckle too closely to cable
supports or other barriers that may hinder proper
operation. Failure to comply with these instructions
could result in death or serious injury.
Install within cable span in same manner as
l
endspring. Use jam nuts to maintain adjustment.
