Distinctive Characteristics
Actual Size JWM
Industry’s first molded rocker with TV rating. Designed to handle large inrush current,
with high electrical capacity of 10 and 16 Amps. JWM models certified for TV-5 rating
and JWL models for TV-8 rating.
JWMW and JWLW panel seal versions meet IP67 of
IEC60529 Standards (similar to NEMA 4 and 6).
Prominent external insulating barriers increase
insulation resistance and dielectric strength.
Uniquely constructed to break light
contact welds.
Increased electrical life with specially
designed plate to minimize contact bounce.
Constructed for dust resistance with interior
cover between actuator and contact area.
Terminals are molded in and epoxy sealed to
lock out flux, dust, and other contaminants.
Solder lug/quick connect terminals can be used
with connector.
Housing and case of heat resistant resin meet UL94V-0 standard.

PRECAUTIONS FOR HANDLING & STORAGE FOR JWMW/LW (PANEL SEAL TYPES)
30°
CorrectIncorrect
Clean Edges
Operating Environment
• Do not install switch where heavy dust collection occurs. Dust build-up under rocker may affect switch actuation.
• Do not actuate switch if submerged in water or oil.
• Installation is not recommended on horizontal surface in an environment where frequent splashing of
water may occur. In such an environment, a minimum 30° angle installation is advisable. If there is
a possibility of freezing, install vertically so no moisture will be retained within switch housing.
Panel Mounting
• Before snapping a switch into the panel, align the gasket evenly under bezel of the switch.
• When mounting into a panel, apply equal pressure to sides of bezel and insert parallel to panel.
• After mounting a switch, be sure there are no gaps between switch and panel.
Lightly push into panel.
• After installing into panel, do not apply excessive force.
• After panel installation and wiring is completed, do not apply force horizontally
or vertically from behind panel.
• Behind the panel, cut area should be squared. If front of panel is painted, do not allow any paint to collect in
corners of cutout to prevent level mounting.
• Avoid reinstalling a switch once it has been mounted in a panel. This may cause deterioration of panel sealability.
