    Perfect for restorations!

    I’ve come across several old houses built with DC controlled/switched AC branch circuits who’s switching relay’s are finally starting to fail after decades of service, so I was quite relieved to find that Remcon Relay Switches are available.
    I’ve used these relays for a few years now with great success, plus they are smaller than the originals so no modifications to the splice box is needed.
    Over-all, this is a wonderful product which I recommend to anyone who requires such a relay, in fact I’m just back to purchase another one for a friends house.

    ✔ Yes, I recommend this product.

    Replacing R-115 with R-115S

    Just replaced the relay in the hallway light, controlled by 3 separate switches. After searching the attic for the relay, I discovered it was insiide the ceiling box and it was an easy job from then on. The only problem was that the 115S being a different shape than the 115, blocked the screw clearances and it required some adjustment to screw lengths to make it all fit. Very happy with the end result after a year of having no hallway light.

    ✔ Yes, I recommend this product.

    Excellent for the job.

    It’s a lot better than the old type, and work more efficiently and last longer.

    ✔ Yes, I recommend this product.
