C&K HB Series
Single Pole Standard Precision Snap-acting Switches
Sealed Actuator and Case
To provide reliable service under environmental conditions that might damage standard precision switches, various HB Series
switch models are sealed against the entrance of airborne contaminants and/or splashing liquids. The clearance between
the operating plunger and the cover is sealed with a silicone boot and the base cover joint is sealed with an epoxy adhesive.
These models are designed to meet requirements of IP65 (dust proof, water splash and dew condensation). For additional
information on sealed switches, consult our Customer Service Center.
