Water Level Float Switch ZP4510 – PP Vertical Type

The Water Level Float Switch ZP4510 is a mechanical liquid level sensor designed for reliable water and fluid detection in tanks and reservoirs. It operates as a dry contact reed switch, changing state when the float rises with liquid level. Rated for up to 220V AC/DC switching voltage and 0.5A switching current, it provides stable performance in low-power control circuits. The PP float and body construction ensures corrosion resistance and submersible operation. Ideal for pump control, alarms, and integration with Arduino, Raspberry Pi, and industrial controllers.
