Eaton Cutler-hammer HT8AEG Push-button Switch 40mm Momentary

Product Description

The EATON CUTLER-HAMMER HT8AEG is a heavy-duty momentary push-button switch designed for industrial and commercial control panel applications. It features a 40 mm mounting hole diameter and a green extended mushroom-head operator, making it well-suited for emergency-stop or machine-control functions where large-target actuation is required. The switch operates on 5 to 28 volts and connects via screw terminals. It carries UL 508 and CSA C22.2 No. 14 listings and is rated for NEMA 1, 2, 3, 3R, 4, 4X, 12, and 13 enclosures, covering both indoor and outdoor wet or oily environments. Electricians and controls technicians install this switch in motor control centers, operator stations, and machine guarding panels.

This switch is a fit for industrial control enclosures requiring a momentary contact operator with environmental resistance. The anti-corrosive, oiltight, and watertight construction qualifies it for washdown, outdoor, and corrosive-atmosphere installations. The NEMA 4X rating makes it appropriate for food processing, chemical handling, or marine control applications where enclosure integrity under direct liquid exposure is required. It is a non-illuminated operator, so no pilot light wiring is needed. Typical installs involve 22 mm or 30 mm panel cutouts on operator workstations, though this unit is sized for a 40 mm hole.
