In the past, old float switches worked by opening and closing dry contacts to send electrical signals that set off a low water level alarm. They used magnetic reed switches that would complete the circuit once the float reaches its lowest point in the water (or when the storage tank is empty). The magnet would disconnect once the water …

Principle of Energy Storage Switch. The so-called energy storage means that when the circuit breaker is de-energized (that is, when it is opened), it opens quickly due to the spring force of the energy storage switch. Of course, the faster the circuit breaker is opened, the better. This is to have enough power to separate the contacts when the ...
