  • Old GE realay switching system

    Anyone have this type of thing - All the lights in the building are controlled from a numbered dial thing at the desk - one turns them on and another turns them off. Each dial has 12 numbers on them. I know its connected to a big stepper relay system in the ceiling that closes the contacts and lights go on or off.
    Having some troubles with the dials and was wondering if this stuff is available somewhere.

    What they are doing is using whats called latching relays. When you select, lets say lights over lanes 1-2 settee, you select #1 position on the "on dial" and push a button under that dial. Its sets the relay on, and it latches to that position (ON). Some systems used dual coil relays to set them on and off, these had three wire connections, one for on, one for off, and common for 24 volt AC. Others had only two wires and would toggle the on/off function every time it was energized.

    Here's what I've come across in most centers: http://westsidedelivers.com/ge_RR7.asp

    The 12 position switches are still pretty common from most supply houses. I used some old DTL scorer swithes from AstroLine Scoring Consoles to make a completely new control box.

    Here's some switches that can be used: http://www.e-switch.com/entity/tabid...y/default.aspx

      Yep, those are the animals I have in here. I thought it was (and was told) this stuff was old and discontinued stuff, but some searching on the internet I see it is still common in large buildings like this one. I have found the PP& relays running anywhere from $10 each (used on ebay) to over $100 each. Thanks for the links Jim.

        Marty - stepper relays and rotary switches fail over the years. This is due to contacts arcing or just getting dirty. In cases like those, it's a lot cheaper and easier replacing the bad components, than it is trying to get them to work.

        There are new solid state latching relays available from many of the suppliers. They're a little more expensive than the mechanical types; however, they'll make up the difference in longevity. Another good point is that, since they're solid state, there are no moving parts to get dirty or contacts arcing. Most solid state relays will "drop right in" without any changes in wiring.
