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-ring below the panel is 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 regard to your application and
intended environment with these properties in mind.
Panel Installation
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 1.5 meters
from the surface and left in
this position for 30 minutes.
Repeat opening and closing
For panel installation,
the internal tooth
lockwasher is
installed above the
panel. The external
o-ring mounts below
the panel.
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.
