Environmental Data
Operating Temp Range: –30°C through +85°C (–22°F through +185°F)
Sealing: Waterproofing, achieved with boot at base of lever plus o-rings inside and outside of bushing, meets IP67 of IEC60529 Standards (dust tight and protection against effects of temporary immersion). See further explanation on last page.
Processing
Soldering: Manual Soldering for SIlver: ON-NONE-ON: See Profile B in Supplement section.
ON-OFF-ON and (ON)-OFF-(ON): See Profile A in Supplement section.
Manual Soldering for Gold, all circuits: See Profile A in Supplement section.
Note: Lever must be in OFF (center) position while soldering.
Distinctive Characteristics
Inner o-ring and external rubber washer seal the switch to achieve
IP67 of IEC60529 Standards (dust tight and water protected for
temporary immersion).
Waterproof boot at base of toggle further ensures protection against
wet environments.
Actuation provides smooth, sturdy tactile feel.
Polished, chrome-plated actuator paired with the waterproof
boot not only delivers in terms of sleek design, but also
functionality and reliability.
Superb quality and construction design prohibit entry of harmful
particles that may otherwise compromise lever operation.

APPLICATION CONSIDERATIONS
The Dual Seal Waterproof M Toggle is designed as a panel seal switch, and not to be used under water.
Material Properties
The material for the waterproof boot is silicone rubber. While
silicone rubber has excellent heat, cold and weather resistant
properties, it has less durability and oil resistance.
The o-rings are made of nitrile butadiene rubber, which
excels in durability and oil and chemical resistance. Its
performance is less durable with lower weather and ozone
resistant characteristics.
Evaluate the products in reguard to your application and
intended environment with these properties in mind.
Waterproof Test Conditions
Waterproofing is measured
by submersing the switch 5
centimeters from the water
surface (see illustration), and
opening and closing 50 times
at a frequency of 50 – 60
times per minute. The switch is
then submersed 1 meter
from the surface and left in
this position for 30 minutes.
Repeat opening and closing
Water Surface
Opening
same as previous test. The resulting insulation resistance and
voltage capacity are both within the rated values, and water has
not entered inside the switch or installation panel.
Panel Installation
For panel installation,
the internal tooth
lockwasher is
installed above the
panel. The external
o-ring mounts below
the panel.
