Float Level Switch SEN-PPI110

💧 Float Level Switch SEN-PPI110
🧩 Overview
Mechanical liquid level detection switch
Uses floating mechanism with magnetic reed switch
Designed for water tanks & liquid level control
Works without continuous power (passive device)
⚙️ Working Principle
Float contains a magnet inside
As liquid level rises/falls, float moves
Magnetic field activates reed switch
Output changes:
ON → level reached
OFF → level dropped
👉 Provides ON/OFF signal for level detection
