Trying to figure out what this symbol means, for context here's the rung on the ladder logic diagram that it was taken from.

You appear to be talking about ladder logic. If so, could you _edit your question to say so_? I would go as far as to suggest that your title should say "ladder logic" in it somewhere. – TimWescott Dec 21 '22 at 15:39

@TimWescott I'm only focused on the symbol meaning. I put the schematic I took it from so that it could probably offer additional meaning. You're certain I should mention ladder logic? – SRR Dec 21 '22 at 15:44

2@SRR Ladder logic uses a *very* different set of symbols than anything else in electrical engineering, so yes, you should definitely mention the context in which you see the symbol. – Hearth Dec 21 '22 at 15:46

What country or region did this schematic originate from? Is it a fluidic (pneumatic or hydraulic) system? The symbol suggests some kind of limit function. – Spehro Pefhany Dec 21 '22 at 16:09

@SpehroPefhany Jamaica. HV422 is a pneumatically actuated valve – SRR Dec 21 '22 at 16:18

1You should add the info from your comments to the question. – StainlessSteelRat Dec 21 '22 at 17:14
