Dayton 22 mm Push Button Enclosure

The Dayton 32W279 is a single-hole plastic enclosure rated NEMA 4 and 4X for indoor or outdoor industrial use. It accepts one 22 mm push button or pilot light head and is listed to CSA, IEC and UL standards. The grey housing measures 1.98 in high by 2.68 in wide by 2.91 in deep with a 1/2 in conduit entry. California Proposition 65 warnings apply for cancer and reproductive harm.

Capacity and headroom

The enclosure provides one mounting position for a compatible RP2B operator or 22 mm push button head, so it covers a single control point. It does not accommodate multiple operators, larger cut-outs or additional conduit entries beyond the single 1/2 in opening. Installations that require several buttons, indicator lights or a higher density of controls will need a larger enclosure with more holes.

Thermals, noise and power

As a passive plastic housing the unit generates no heat, produces no noise and draws no electrical power in normal operation. Thermal performance depends entirely on the installed operator and the surrounding ambient conditions. The NEMA 4X rating ensures the enclosure resists corrosion and water ingress without active cooling.

Questions about this item

Will the 22 mm hole accept the RP2B operators I already have?

Yes, the enclosure is designed for RP2B operators and plastic 22 mm pushbutton or pilot light heads.

How can I verify the NEMA 4 and 4X rating is met once installed?

Confirm the conduit seal at the 1/2 in entry and ensure the gasket seats evenly; the UL, CSA and IEC listings cover the enclosure itself.

Does the box include the pushbutton head or just the gray plastic enclosure?

Only the enclosure is supplied — the 22 mm pushbutton or pilot light head must be purchased separately.
