Relay switches I visited an open house next to a former friend's house in the neighborhood I grew up in. I always was curious about it as it had some interesting outdoor lighting and was the first house I ever saw with a solar panel on the roof. It's a huge house, and was owned by an electrician originally; as you can see, all the lighting is controlled by relays and note the triplex outlet. I didn't get a picture of the neon glow lamp on the ceiling outside the kitchen (not sure why it was there) nor the T12 slimline 4' & 8' shoplights in the basement shop, or the collection of vintage T12 slimline lamps, but this place was a goldmine.

Forgot to mention the dining room dimmer switch was a huge theatre-style dimmer that reduced the voltage, not your ordinary triac-style.

Only an electrician would have the idea to install 24V lighting control systems! That's the kind of thing you usually see in commercial buildings, mainly on 347V circuits, or 277V.

If my eyesight is good, that seems to be the GE system. Technically I'm qualified to install them, along with Douglas systems!

My school has the same relay system, seems they were quite common in the 1960s and 1970s as I've seen another house built during that time with relay switched lighting.

That house used twin momentary contact buttons like the start-stop buttons on a motor control instead of a rocker switch.

Hmm my schools have all just been 120V Razz Why would the electrician have put relays in his home though? Seems kind of pointless to me and a waste of money too when a regular switch does the same thing. Unless everything in the house if run of one circuit. Razz Laughing

I know on some systems, there's a master control panel that has buttons to control all the relays at once, I guess it was an early form of centralized lighting control seen in home automation systems.

As for my school, they used relays since the lighting was 347v and to allow the projection system to control the lights. It's pretty neat, there are different lighting presets in the rooms for video, teaching, etc.

Ah I see. Relays do sound cool if they can do all those things!

Does he still own the house?
