Industrial Selector Switch, 30 mm, 2 Position

The Eaton HT8JAH3A is a short-handled selector switch built for industrial electrical control panels. It mounts in a standard 30 mm cut-out and provides two maintained positions for manual circuit selection. The operator head and bezel are metal with a chrome finish, while the knob itself is black. This component is rated for new condition and carries CSA and UL certifications.

For Panel Builders Needing Maintained Two-Way

This switch suits engineers and maintenance technicians wiring motor controls, lighting circuits or process equipment where a maintained two-position action is required. The IP65 and NEMA 1, 2, 3, 4, 4X, 12, 13 ratings allow installation in wash-down areas, outdoor enclosures and dusty production halls. Buyers who need a momentary return action, a key-operated mechanism or more than two switching positions should look at a different device.

Cam 3A Determines the Contact Sequence

The cam code 3A defines the internal contact arrangement and switching sequence for the two maintained positions. Verifying this cam against the wiring diagram is the single step that confirms the switch will perform the required logic in the panel. If the schematic calls for a different cam profile, this part will not match the design.

Questions about this item

What does the 2-position maintained action mean for everyday use?

The knob stays in whichever of the two positions you turn it to, so the connected circuit remains on or off without spring-return.

Which NEMA and IP ratings does the 30 mm operator carry?

It meets NEMA 1, 2, 3, 4, 4X, 12 and 13 plus IP65, giving protection against dust, water jets and corrosion in industrial panels.

What panel cut-out and bezel size suit this 30 mm selector?

It mounts in a standard 30 mm cut-out and the chrome metal bezel covers the opening for a flush, finished appearance.
