Re: Momentary / low volt lighting
It sounds like a very commonly installed system, the name of which escapes me at this time.
GE still makes the parts.
The relays are mechanically latching and have three small leads on them for the control voltage.
Common, open, close and just need a momentary 24 VAC signal to operate them.

I kept having visions of 1,200 amp services in 1000 sq ft homes for SA circuits.
Thanks, and what a long strange trips it's been.Originally posted by physis:

Worked out well for you then.Originally posted by physis:

Touch-Plate systems have been around for quite a while and are very common in home built in the 60?s. The system is very similar to the GE equipment Bob is referring to.

Re: Momentary / low volt lighting
There must have been an EC installing the low voltage switching in my area back in the day. Both GE and P&S still make the switches and relays. The switches are available in despard style and regular snap switch style. The snap switch style looks funny because the switch toggle sticks straight out. Lithonia makes special panels to mount the relays in and they make master and slave control modules for the low voltage switching. Basically, the switches have three terminals... common which makes with terminal 2 in the "up" position or terminal 2 in the "down" position. The relays have three terminals also, since they latch. One wire goes to one lead of the 24 volt transformer. The other two leads correspong with "on" (terminal 2) and "off" (terminal 3) on the switch(es). The switches are WIRED IN PARALLEL. Throw everything you know about 3 ways and 4 ways and such out the window with this type of system. Some of these systems also have a small rectifier to run the relays on DC for greater reliability (same relay).
