I picked up this switch from Lupica this morning. Looks like a 240 switch but I can't identify it.

Here's the back.

I want to say headlight wipers but honestly I've never seen it before

Neat, I have never seen one before either. Headlight wiper seams plausible given a quick Google reveals that general style of switch was used for that purpose and in general Volvo switched a bit between using words and pictures.

It's for Delorean.
Lots of Volvo in them.
