A float switch is a device used to sense the level of liquid within a tank. The switch may actuate a pump, an indicator, an alarm, or other device.
It can be easily converted from normally open to normally close by inverting the float.
Note: because the current that the switch can carry is much little(3A), you must use a relay or contactor when it is connected by a load, relay and contactor are not included here.



  • Max Switching Voltage : AC110V; Float Ball Size : 26x26mm; Wire Length : 250mm; Screw : M11
  • The float switch can be installed at the top or bottom of the tank, depending on whether you want to detect water rising or falling.
  • Floating ball switch is a kind of liquid level control device with simple structure and convenient use. It has the advantages of small volume and long working life compared with general mechanical switch. When selecting the right material, any kind of liquid, pressure and temperature can be used.
  • Widely Applications: For tank / pump water level control;For fish tank and aquarium system; Used for water level control of household appliances;Used for water level control of swimming pool, fountain, pond, waterfall, etc.
  • Please Note : Float switch can not directly control solenoid valve or high power relay, AC contactor, etc. Small relays are required to transition.
