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.
Switches with 1 AMP rating (option
code ‘F5’) are available only with
.020 contact separation (option ‘2’).
Switches with 1/2 HP, 125 V AC rating
or greater (option codes ‘B5 and B6’)
are not available with .010 contact
separation (option code ‘1’).
