    Hi All. I've been looking for a SPST (form A) power relay that can operate at low temperatures, i.e. at least down to -50 Celsius. The one I need would have a 5VDC coil and 15A contacts. I've found a few with these specs but none that are rated to that low a temperature. This will be used in the Canadian prairies in the winter so it needs to operate at painfully low temperatures. Any suggestions would be highly appreciated. Thank you.

    I would talk directly to Newark, Allied or Digi-Key. Ask about MIL-Spec temp ratings for relays they should be able to fix you right up.

    Did you also had a look for "solid state" relays? Maybe an option, even though I didn't find one having a quick look at digikey.

    Thanks all. I did contact Digi-Key and they got back to me today after I already posted this. They recommended the following parts in cases anyone else is interested.
