KELLOGG ITT 530 Select O Phone

[Jim Stettler]

My guess is it  switches between voice and output (automation) circuits.
This phone system provides output circuits (control circuits). Relay outputs to trigger lamps ,bell, or other control relays.
You could configure  this phone system to shut down your production line. Cool things like that.

Really good info Jim...you are right, the Select O Phone did do some cool things. Well ahead of its time, indeed! ...Doug

I believe that one of the functions of the button was to ring the phone at the other end.  Somewhere in the archive is a Select-O-Phone manual.

The phone looks really nice.

I've got the wall version of the Kellogg Select-O-Phone.  It has the same DC ringer, but is missing the switch.  I assume it has the non-standard dial, I haven't tried to figure it out.

There is a late model Selectophone on Ebay, new old stock in black.

Dated 6-76, with the DC ringer.
I didn't think they made them this late.

Wow!  Is that wall version Dark (Oxford) Grey?  Hecka rare!

Mike, if you are referring to the previous post, that's my dark gray Selectophone. It's missing the switch; I put a chrome cap in the hole for now. It looks good, but isn't very useful. It's still my only dark gray phone.
