Auto Switch Schematic Symbol

I would like to know if anyone knows of a proper schematics symbol to use for a 3 wire magnetic auto switch. This is the kind of switch you would use on a pneumatic cylinder to detect position.

I have used a standard prox sensor symbol in the past but I was wondering if there is something better.

I agree with James. To indicate that it is magnet operated, some people put a C shaped magnet symbol above it. I am more inclined to include that info in the description and use the standard prox switch symbol.

I think this one is IEC and yours is JIC, but I didn't find a JIC version with the magnet in a quick google search:
It's not all the variables I am most concerned with, it's the undiscovered constants.

Like all of the previous replies, I agree that symbol is foe a prox switch. I’m not sure what you mean by using the word “auto” though.
