Advanced Overflow Detection: The SS2 Float Switch is specifically designed for air conditioning systems to monitor and prevent condensate water overflow. It effectively detects blockages in the condensate drain pipe, automatically shutting down the system to protect your property from water damage to floors, walls, and ceilings. Operational Mechanics: This float switch operates as an NC (normally closed) unit. Under normal conditions without water overflow, the float remains at the bottom, keeping the circuit closed and signaling ON. In the event of water reaching overflow levels, the float rises, triggering the switch to open the circuit and signal OFF, thereby preventing system overflow. Robust Specifications: Constructed from durable PVC, the SS2 Float Switch operates within a temperature range of -20 to +80℃. It features a 5.8ft wire, can handle a maximum switching voltage of 200VDC, a switching current of up to 1A, and a contact rating of up to 10W, ensuring reliable performance under various conditions. Installation Simplicity: Installation of the SS2 Float Switch is straightforward. It comes with a 3/4 inch adapter for easy attachment to the auxiliary drain outlet of your main panel. Simply connect the included 5.8ft wire to your VCC or thermostat line to integrate seamlessly with your existing air conditioning setup. Note:There may be slight chromatic aberration in kind.
