Enclosed Switches
WARNING
PERSONAL INJURY
DO NOT USE these products as safety or emergency
stop devices or in any other application where failure of
the product could result in personal injury.
Failure to comply with these instructions could
result in death or serious injury.
GENERAL INFORMATION
OP switches are used in applications where the splash
of oil, water or other liquids might hamper the operation
of less-adequately protected switches. A gasket
between cover and housing plus an O-ring shaft seal
provide the seal for OP switches. OP switches are NOT
explosion-proof.
Rotary OP's sealed construction provides protection
from the entry of dust, water, oil and noncorrosive
liquids as defined in NEMA 1, 3, 4 and 13.
Since "Q" plunger actuators are not sealed, it is
recommended that the switch be mounted so that liquids
will not fall directly on the plunger. These plunger
actuators meet NEMA 1 enclosure requirements.
INSTALLING THE SWITCH
A mounting bracket (15PA85-EX) is furnished at no
extra cost with most OP switches. This permits all rotary
operated switches to be mounted from top, bottom, back
or right end. Plunger switches may be mounted on back,
bottom or right end with this standard bracket. For top
mounting of plunger switches, bracket 15PA86-EX must
be purchased separately.
ELECTRICAL RATINGS
Electrical ratings of OP switches depend on the type of
basic switch enclosed in the housing. Ratings are shown
on page 2 along with letter keys (A, B, C, D) shown in
table of listings on page 3.
