22mm Push Button Lift Off Cover

PB35-22mm SERIES

Oil & Dust Tight Pushbutton Enclosures

Ralston’s PB35-22 pushbutton enclosures are designed to provide protection against dust, dirt, and oil for most standard oil tight pushbuttons, switches, and pilot lights.

All PB35-22 enclosures are made from 14 ga. cold rolled steel and have continuously welded seams ground to a smooth finish. Each enclosure comes complete with grounding studs and wall mounting back brackets welded to the top and bottom outside.

The door is prepunched to accept 22mm switches, pilot lights, and pushbuttons.

The doors are sealed with oil resistant neoprene gasket and are secured to the sealed (blind) rivnuts in the enclosure with 10-32 captive screws.

Paint Finish
All enclosures are phosphatized and finished inside and out with ANSI/ASA 61 grey polyester powder coating.


PB35-22mm enclosures are built to the requirements of NEMA/EEMAC Type 12 specifications for use with industrial controls in ordinary locations, and type 13 for an oil and dust tight enclosure.

PB35-22mm enclosures are CSA certified (file #23608) and UL 508 Listed (file #136838) as a type 12 enclosure.
