Thereof, what is a tethered float switch?
A. There are basically three types of float switches: Tethered, vertical, electronic. The tethered style float switch is great for larger diameter, deeper sump pits. They allow the pump to be off longer between pump cycles so the motor can cool off more completely.
What is a float switch on a water pump?
A float switch is a type of level sensor, a device used to detect the level of liquid within a tank. The switch may be used to control a pump, as an indicator, an alarm, or to control other devices. One type of float switch uses a mercury switch inside a hinged float.

The purpose of a float switch is to open or close a circuit as the level of a liquid rises or falls. Most float switches are “normally closed,” meaning the two wires coming from the top of the switch complete a circuit when the float is at its low point, resting on its bottom clip (for example, when a tank is dry).
