[Compact Liquid Level Sensor Float Switch]: Small size, simple wiring, low power consumption; Total Cable length: Approx. 40cm / 15.7inch [Well Performance]: Strong anti-interference with high stability, on-toxic, corrosion-resistant; Working Voltage: 110V, Working Current:3A, Working Temperature: 30~80, Max Temperature: 85, Working Pressure: 1Mpa, Max Pressure: 1Mpa [Easy to Use]: Easy to install, convenient to use, and long service life; Float switch is mainly composed of a magnetic spring switch and a float. There are magnetic materials in the float. When the float moves up and down with the water level, it will touch the magnetic spring switch to detect the liquid position [Wide Application]: Float switch can be used for water heating equipment such as water dispenser, water heater, humidifier, etc. It also can be used for water tower, drainage pool, water tank, culture pond, etc [Note]: Because the current that the switch can carry is much little, you must use a relay or contactor when it is connected by a load, relay or contactor are not included here
