Eaton 10250TA55 30.5 mm, Heavy-Duty Pushbutton Operator

Yes. The operating mode is latched by a padlockable attachment in the down position, and the button is spring loaded, so once it is pushed in and the attachment is padlocked, the circuit stays held until the lock is removed. That is what makes it usable as a lockable stop rather than a plain momentary button.

Washdown and wet locations, yes. The operator carries NEMA 3, 3R, 4, 4X, 12 and 13 ratings, which covers rain, hose-directed water, corrosive washdown (4X) and dust or oil-laden industrial air. One caution for outdoor use: the jumbo mushroom head is plastic and is not recommended where it sees ultraviolet light, so direct sun exposure is the wrong application even though the seal rating allows the environment.

The 10250TA55 is an operator only, meaning the red jumbo mushroom head, chrome bezel and padlockable latching mechanism. The contact blocks that actually switch your control circuit are ordered separately from the 10250T line and stacked on the back, so plan your NO/NC count before you order.

No, it is a non-illuminated operator. There is no lamp or LED behind the head, so you do not need to supply a voltage to the device itself. If your panel drawing calls for an illuminated mushroom head, this is the wrong part number.

Plan the layout around 4.4 inches by 3.4 inches by 3.2 inches overall, with the unit weighing about half a pound. The jumbo mushroom head is the widest element, so spacing on a crowded door matters more than depth on this one. Adding contact blocks will extend the depth behind the panel beyond these figures.

A jumbo mushroom head is the right choice when the button has to be hit fast, with a glove or a palm, and then stay held. The 10250TA55 gives you that large red head plus padlockable latching in the down position, so an operator can strike it and a technician can lock it out. A flush or extended button is better where you want a momentary jog or start signal and want to avoid accidental actuation.
