Latching relays are widely used in various industries due to their ability to maintain a switched state without continuous power. Unlike conventional relays, latching relays only require a short pulse to change states, making them highly energy-efficient. This unique feature makes them an ideal choice for applications requiring low power consumption, reliability, and long-term durability.
In this blog, we'll explore the industries that frequently rely on latching relays and how they benefit from their use.
