When water raises the float this opens the connection. These float switches go bad every so often. In the case where the switch has gone bad and you are sure you do not have condensate clog in your line, you can cut the wire at the top of switch and twist together the wire to the unit and cover with a wire nut. You are going to have the switch replaced anyway, so you might as well enjoy your A/C without paying for an emergency visit from your local HVAC professional. Do this only if you are 100% sure you do not have a clogged line. I take no responsibility if your line is clogged and you suffer water damage. **Q: Can this be put into a secondary drain pan that sits under the ac?** A: I don't see why not. Just make sure you have the wiring set up correctly to shut down the unit. I assume there is another switch in the primary drain pan. **Q: Can the float level be adjusted, by rotating the float shaft on a thread(?), or ?** A: No, I don't believe it is adjustable. Since it is designed as a type of safety switch (to turn off AC unit) there isn't a need to adjust. **Q: What is the inside diameter of the pipe that the switch slides into? Does the switch use a float?** A: 3/4 inch id. switch does use a float ## Frequently Bought Together - Rectorseal 97637 Safe-T-Switch Ss2 - Rectorseal 97647 Safe-T-Switch Ss3 - Rectorseal 97632 Safe-T-Switch Ss1,Black/ White --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/6446448-safe-t-switch-97637-condensate-overflow-switch-easy-access-condensate](https://www.desertcart.at/products/6446448-safe-t-switch-97637-condensate-overflow-switch-easy-access-condensate) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-11-02*
