Pressure switches

I have a few of these Dwyer Magnehelic differential pressure switches I’ve been dragging around since the 80’s. If anyone has any use for them just send a pre-paid self addressed USPS box and they are otherwise free.

Same goes for these Fireye flame sensors. The ones I have are the same as the 45UV5 in this l ink.

If you are interested just PM me. I’ll check the weights for the packaging.
