Description
  • The P31-FLOAT-SWITCH is a compact, reliable mechanical float switch designed to detect and control liquid levels in tanks and reservoirs.
  • It operates using a buoyant float connected to an internal switching mechanism. As the liquid level rises or falls, the float moves accordingly and toggles the internal reed switch.
  • This switching action can be used to trigger pumps, alarms, valves, or controllers in water management and automation systems.
  • The switch is built using P.P. (Polypropylene) material, offering excellent chemical resistance and suitability for a wide range of liquids including water, oils, and mild chemicals.
  • Since it is mechanical and passive, it requires no external power, making it ideal for remote and industrial environments.
  • Its simple design ensures easy installation, low maintenance, and long-term reliability.

PACKAGE INCLUDES:
  • 1 x P31 Small Float Level Control Switch (Plastic Float Switch)
