Safe-T-Switch SS3 Condensate Overflow Shut-Off Switch for HVAC Systems

Protect your home, business, and HVAC equipment from costly water damage with the Safe-T-Switch SS3 Condensate Overflow Shut-Off Switch. Designed for use in both primary and auxiliary drain pans, the SS3 automatically shuts down your air conditioning system when condensate overflow or drain blockage is detected.

Whether you're installing a new HVAC system or upgrading an existing condensate management setup, the SS3 provides reliable overflow protection using a proven magnetic reed switch and adjustable ratcheting float mechanism. By stopping operation before water can escape the drain pan, this simple yet effective safety device helps prevent ceiling damage, mold growth, drywall repairs, and expensive service calls.

Why Every HVAC System Needs Overflow Protection

Clogged condensate drain lines are one of the most common causes of residential HVAC water damage. Algae buildup, dirt, dust, and debris can restrict drainage and cause condensate to overflow into attics, ceilings, walls, and living spaces. The Safe-T-Switch SS3 provides an additional layer of protection by automatically shutting down the cooling system before overflow becomes a costly problem.

Many HVAC professionals consider condensate overflow switches an essential safeguard for systems installed in attics, closets, utility rooms, and other locations where water leaks can cause significant property damage.

Great so far
Size: 6 FT, Color: White
The first thing I liked about this is that the on/off switch has a mark on the ON side, unlike my last Belkin power strip, which had a switch where you couldn't tell which side was on or off. That Belkin was remote, which I really wanted, but the Belkin remote never worked reliably even from the start, so I'm happy with a surge protector without a remote but where I don't have to guess whether it's on or off if I can't see the light on the device plugged into it. Very reliable and solid performance so far and I also especially like the generous amount of space between the outlets - enough for the biggest plug without getting crowded. Also it's not heavy & clunky like some. And the 6 foot cord length works great, too - a big difference with the usual 5 foot cord. Also has 2 USB slots which I can use to charge my iPhone and USB chargers. All this at a decent price and it's not clunky or ugly. Have been using it daily all day for 3 months now with zero problems.

Very Good Purchase
Size: 10 Ft, Color: White
I bought this for my fiancee at the time who had several things to plug in, but did not have the space and would keep rotating plugs. This was able to help her organise the place better and charge multiple things at once. She absolutely loves it. It even has ports for phone chargers, which is very useful. The quality is very good as well. Strong and durable and looks good once you take care of it. Can blend in well and it looks good aesthetically.
