Resists penetration of dirt
and dust into the Switch.
No protection against gases,
or water, oil and other liquids.
Use a Sealed Switch or a
Limit Switch if the Switch
may be subject to water or
other liquids.

Basic Switches prevent
penetration of dirt and dust
generally by minimizing gaps and
using interlocking construction
for the actuator section (case
and push button), gap between
case and cover, and terminal
section.

Complete dust proofing by
eliminating gaps in the
actuator section, between
the case and cover, and in
Switches. Resistant to gas.
The terminal section is
exposed, however, so
caution is required for water
and oil.
D2JW Model

Excellent resistance to dust
and gas by eliminating gaps
in the actuator section,
between the case and cover,
and in Switches. The terminal
section is exposed, however,
so use a Sealed Switch or a
Limit Switch if the Switch
may be subject to water or
other liquids.

The actuator, gap between
case and cover, and terminal
section are all sealed. High
resistance against dirt, dust,
gas, water, and other elements.
