B-Line 10250T75W Assembled, 30.5 mm Pushbutton

Momentary. The button makes contact only while it's held and drops out when released, so it suits start, jog, or call functions rather than a latched on/off. If you need the circuit to stay made after release, you want a maintained or push-pull unit instead.

The light unit is built for 120 Vac and uses an incandescent lamp with a transformer, so it wires directly onto a 120 V control circuit with no separate supply. It is not a 24 V device.

One normally open contact block, 1NO. It closes one circuit when pressed. For a second circuit, or for a break contact to stop or interlock something, you need an additional 10250T contact block added to the operator stack.

Its enclosure ratings are NEMA 3, 3R, 4, 4X, 12 and 13, which covers outdoor rain and dust, hosedown, corrosive washdown, and oil in industrial areas. The device rating holds only if the enclosure it mounts into carries the same rating and the gasket is seated properly.

Extended actuator, white plastic, with a chrome bezel. The raised button stands out from the bezel so it's easy to find and press with a glove, which is why extended buttons get used on machine consoles. If you need to avoid accidental operation, a flush button is the better choice.

It's part of the 30.5 mm heavy-duty 10250T family, so the operator footprint, panel hole and contact blocks are common with the rest of that line. The colour here is white with a chrome bezel, which is typically used for a neutral indication or a general function rather than start (green) or stop (red), so check what the legend plate on the existing stations calls out before standardising on white.

No. The light unit is a separate 120 Vac circuit from the 1NO momentary contact, so the lamp is driven by whatever you wire it to, typically a run or status signal, and stays lit independently of whether the button is being pressed.

Because it's an incandescent light unit with a transformer, the lamp is the wear item, not the operator. Replacement is a 120 Vac incandescent lamp for the 10250T light unit, and the assembled operator and 1NO block stay in the panel.
