Features:1. Reliable liquid level detection using a magnetic reed switch mechanism.2. Compatible with water pump tanks, water dispensers, water heaters, humidifiers, water towers, and breeding ponds.3. Suitable for both low-pressure (max 10W) and high-pressure (max 50W) applications.4. Wide temperature range: -20°C to +60°C for low pressure, -50°C to +90°C for high pressure.5. Includes 2 units for convenient installation or replacement.Product Details:The float switch consists of a reed switch and a float with built-in magnetic material. As the water level changes, the float moves and triggers the reed switch to detect liquid position. Note: The switch carries only a small current (0.5A), so a relay or contactor is required when connecting loads (not included).Specifications:- Pack Quantity: 2 pieces- Low Pressure: Max power 10W, end-of-stroke voltage 110V DC, max switching current 0.5A, min collision voltage 220V DC, max load current 0.5A, temp range -20°C to +60°C- High Pressure: Max power 50W, end-of-stroke voltage 220V DC, max switching current 0.5A, min collision voltage 300V DC, max load current 1A, temp range -50°C to +90°C
