## Description

Product Specifications: 1. Product Name : Water Level Sensor Float Switch 2. Material: stainless steel 3. Switching current: 0.5A 4. Max switching voltage: 100V 5. Maximum Temperature:120° 6. Color: Red， Silver 7. Thread Dia(Approx) : 10mm 8. Switch Body Size (Including thread): 215 × 28 mm (Max H × D) 9. Cable Length : 32cm 10. Weight：67.6g 11. Widely used in electronic, electrical, chemical, water treatment, drainage, level control and alarm. Note: The point of the float is fixed, and there is a circlip limit on the upper and lower sides. The reed switch contacts inside are not movable. The reed switch contact current inside the float switch is small, and the large load will burn out. Control the solenoid valve, the alarm should be added with a small relay, and the control pump should be equipped with a small relay and an AC contactor. Packing List: 1 x Stainless Steel Floating Switch

Review: Disappointed it worked only for less than 2 months - Worked only for a month and a half. Probably actuated 4 or 5 times a day... low voltage low current. Triggered cleaning on my koi pond and almost caused my pond to get pumped dry. It looked well made but it really should have lasted longer. No longer closes circuit and have no idea why.
Review: Arrived swiftly - Arrived on time and works well
