Sorry for the slightly off topic post (however this is for a machine installed inside my airplane hangar).

I am looking for a pushbutton switch to replace the broken one on my hydraulic lift.Â

It's a push button momentary contact on single pole single throw switch.  The diameter of the hole in the panel is 0.894 inches / 22.72 MM.Â

The switch that broke is labeled CHNT NP4 and it has other numbers on it such as GB140 48.5 and it's a 10 amp switch. Â

It is a switch that you push and hold in the button and then a relay closes to energize the electric motor that moves the hydraulic pump.

Again, sorry about the off-topic post however I've spent 30 minutes on the Google  with no success but I'm sure there's a guy on this forum that will recognize this switch immediately and know exactly where to find one (or one that will work).

Thanks!!!Â

There is nothing electrically special about this
switch other than the fact that it's normally open.

You probably want to get the door operable ASAP
so go to a hardware store and get ANY normally open
P.B.  Here's one example at Lowes.

Wire it into place temporarily . . . mgiht even let it
dangle on the wires wrapped with tape to keep the
electrons from tunning onto the floor.

Then order one of these:

It will directly replace the switch that's broken
and will be delivered to your door in a few days
for free.

Hi Bob,

You might want to recheck that ebay link. When I click it, I get an emergency stop switch. The industrial E-stop switches I've worked with latch down, opening the safety interlock line and closing a pair of contacts used for monitoring the safety loop. They must be either pulled or rotated back to 'normal' position. The one pictured has circular arrows on the button, which indicates that it latches down and must be rotated to release. The text at the bottom of the listing says that, too. If he's replacing a momentary PB, things could get interesting if he doesn't notice how to release the button.
