Hammond Manufacturing: Type 12 Mild Steel Miniature Pushbutton Enclosures, MPB Series

January 17, 2023

Introducing the new Type 12 mild steel miniature pushbutton enclosures from Hammond Manufacturing, designed to accept 22mm miniature oil tight pushbuttons, switches and pilot lights, and provide protection for them from dirt, dust, oil and water.

These pushbutton enclosures are formed from 14 gauge steel (with the exception of the MPB1, which is 16 gauge instead), with smooth continuously welded seams, welded brackets for enclosure mounting, and captive cover screws which thread into sealed wells. Larger enclosures provide internally hinged removable covers which are designed to hold the cover open during wiring. These enclosures also come with oil resistant gaskets and adhesive, and possess bonding studs on the door and grounding studs on the enclosure.

  • CSA Type 12 and 13
  • Complies with
    • NEMA Type 12 and 13

  • Appropriate components are required to maintain these standards.

The MPB Series pushbutton enclosures are offered in ANSI 61 gray and RAL7035 light gray powder coating.
