The RectorSeal SS610E Safe-T-Switch is engineered specifically for mini-split systems, offering a reliable safety switch for HVAC drain pans. It operates across a wide voltage range and includes an onboard LED indicator that can be mounted to the side of the unit. The sensor connects to indoor units and can be installed directly on the primary drain pan or clipped to coils above it. The switch is versatile, capable of being wired in both normally open and normally closed systems, and operates without the need for batteries.
