Yellow Normally Open Mechanical Float Switch

The JHY20U1000 is a mechanical float switch that is typically open. Mercury is not used to close and open this type of float switch.

Rather, inside the float, a metal ball rolls back and forth. The connections within the float switch will close when the ball rolls to one side. The contacts will open when the ball rolls to the opposite side.

This float switch will be in the open position when it is suspended from its tether. It is known as a normally open float switch as a result. The float switch will begin to float upward and close when the water level rises.

This kind of float switch is frequently utilized when a tank needs to be periodically drained. The float will be open and no electricity will be delivered to a pump inside the tank when it is empty. The float switch will shut off and supply electricity to the pump when the water level rises. The water level will then drop as the pump drains the tank of water. The switch will open and turn off the pump when the water level falls sufficiently low. This is where the cycle will begin anew.
