A need a limit switch with two outputs. When the switch is in one position it closes a contact and when it is in a second position it closes a different contact. Using logic to show that if it is not on, it is off, is not sufficient for the application. I can't seem to find such a switch. Maybe I'm not describing it correctly? Thanks for any help.

 

I don't recall having run into one either.

Partial turn actuators have end stop limit switches and can typically be purchased with addtional, optional, external position switches and the optional position switches are totally independent of each other.

I'm guessing that the complexity of mechanical positioning to achieve dual purpose limit switching is so complex that it limits the commercial availability of a 2 position limit switch.

Mechanical pressure switches offer dual switches at the trip point, but that's done with a second microswitch.

 

Are you trying to detect two positions or three? For two positions a limit switch with a normally open and a normally closed contact, or changeover contact will do the job.

 

Just a thought, is it possible to just use two switches? The plant where I work uses a two switch setup on a few different machines to have inputs for a home position and an overtravel position. The plunger type switches with a roller on top are very close to each other but stacked side by side. A stepped steel piece is used on the moving part to trigger them.
The switches look like this:

So I'm not certain if I got your description right, and I'll apologize ahead of time for that. But anyways I believe youeant that you are seeking a switch that, in theory would be actuated by something moving in the SAME direction that actuates a first set of contacts ( N.O / N.C. ) and... as it moves along further then actuates a second set of contacts ( N.O / N.C.) within the same limit switch... and I'll assume for clarification the first set of contacts are still held in position because what's moving over the limit switch is long enough / large enough to keep the first set of contacts actuated, correct ?

Short answer. No never heard of such a limit switch capability.

But again, I don't know everything even though I've been around for a good long time.

Please let me know If I got your request right... I'd hate to think you meant something else.

Have a good day.

I immediately thought of using 2 limit switches as well.. But I have no clue how much room there is was to do what he needs... But yeah, 2 switches would be a solution

Alrighty then.

That sounds like a double-throw (SPDT) limit switch, one contact closes in one position and the other in the opposite. Have you checked if industrial roller-type limit switches fit your setup, and would you need it to handle any specific voltage or load?
