This High Temperature Water Level Float Switch is designed for reliable liquid-level detection in tanks, wells, reservoirs, chemical containers, and industrial process systems. Its rugged float design and integrated microswitch provide stable on/off control for pumps and valves, even in challenging environments.
The switch uses a heat-resistant silicone cable (rated up to 180°C) with a 1.0 mm² thick conductor, ensuring long-term durability, excellent insulation, and strong resistance to aging and harsh environmental conditions. Inside the float, a precision micro-switch with a composite silver contact ensures accurate actuation and high switching reliability.

| Function | Details |
|---|---|
| Wire Color – Blue | Control wire used for water-filling mode (activates when float is down). |
| Wire Color – Brown | Control wire used for water-draining mode (activates when float is up). |
| Wire Color – Black | Common wire shared by both filling and draining modes. |
| Blue + Black Operation | Float Down (low water level): Circuit closed (ON), pump starts. Float Up (high water level): Circuit open (OFF), pump stops. Used for water-filling systems. |
| Brown + Black Operation | Float Up (high water level): Circuit closed (ON), pump starts. Float Down (low water level): Circuit open (OFF), pump stops. Used for drainage / sump-pump systems. |
| Water Supply System (Filling) | Use Black + Blue wires. ON: Float at low level. OFF: Float at high level. |
| Drainage System (Emptying) | Use Black + Brown wires. ON: Float at high level. OFF: Float at low level. |
