[GreenKeys] RE: what is a polar relay?

[amourdutigre]

Thank you all again for the help with this. I had no idea that the landlines used polar signaling. I simply thought that they blasted a make/break signal with lots of voltage to compensate for the high resistance steel wires. Now it seems to make sense to me.

As far as the relay on e-bay, I suspect that the seller is an antique dealer, and often antique dealers have very little idea what an object is worth. They either charge way too much for the item, or sometimes, the item is very valuable, and they will sell it for far less than what it is worth. I guess that anything is worth only what somene will pay for it though. As for me, I will not pay $140 for that relay, with a nice $70 on top of that for shipping. (This is one of my real complaints about e-pay...there are those out there that use the shipping charge to up their price in a semi-stealth way. I once bought a Heath SB-301 and the seller only charged me 7 dollars to ship. This guy wants 70 to ship a relay that I would dare say weighs a whole lot less than the '301 does.)

Thank you a again for the information!

Best and 73
