Mini Right-Angle Water Level Float Switch | Compact Liquid Level Sensor for Tanks, Arduino & Smart Water Control Systems

Product Description

The Mini Right-Angle Water Level Float Switch is a compact and reliable liquid level detection sensor designed to monitor water or other non-corrosive liquids in tanks, reservoirs, and automation systems.

Built with a right-angle mounting design, this switch can be easily installed on the side walls of tanks or containers. It works using a magnetic reed switch mechanism — when the float rises or falls with the liquid level, it opens or closes the circuit to trigger a control device such as a pump, buzzer, or indicator LED.

Lightweight yet durable, the switch is made from corrosion-resistant materials, making it suitable for Arduino projects, IoT water control systems, and industrial liquid monitoring.
