What Is a Low-Voltage Switch?
A low-voltage switch is designed to disconnect the power supply when the voltage falls below a predetermined level.
This switch is primarily used to prevent over-discharge in batteries. It functions by cutting off power to the load when a battery’s voltage drops below a certain threshold, thus helping to prolong the battery’s lifespan. It also plays a key role in protecting equipment.
There are two main types of low-voltage switches: relay-based and diode-based. Relay-based switches, which use a relay for disconnection, are known for their high durability and reliability but tend to be more expensive. Diode-based switches, using diodes for power cutoff, offer a cost-effective solution but may have slightly less durability and reliability in comparison to relay-based switches.
