8906K4519 Circuit Interrupter Switch

[warf]

Hello;

I have a question about the 8906K4519 Circuit Interrupter Switch.

Every time I turn on the generator I have to move this switch to the CLOSED position and it self centers after. Is this the way is supposed to work? I have read here that that particular switch almost never goes bad, but, could I have a bad switch?

If it won't harm anything, I would like the switch to stay in the CLOSED position. Is this possible and advisable to do?

Thanks

Short answer: it's normal, and holding closed is a not so good idea


Long answer:
These are momentary switches. So the return to center is normal. The way these circuits work is electrically held. Meaning when you select closed the contactor closes and electrically holds itself on until tripped or manually opened.

If held to close, depending on the system wiring, can cause the contactor to not trip (due to the close command) or rapidly open and close.

Ps: it's very helpful to list what set you are working on.

Why would you want it to stay in the closed position?
