What type of relays can be reset electrically?

Latching relays are designed to maintain their state after being energized until they are reset. This reset can be accomplished electrically by applying the appropriate signal or voltage, which allows them to switch from one state to another without continuous power. This characteristic makes latching relays particularly useful in applications where it is important to conserve energy or where a circuit needs to maintain its state without a constant power supply.

In contrast, reed relays typically operate as electromechanical switches that open or close in response to a magnetic field without the same capability for an easy electrical reset. They return to their default state when the magnetic field is removed. Walking beams and hoist motor fields are not standardized types of relays and do not inherently involve an electric reset mechanism.

The unique ability of latching relays to be electrically reset is integral in many control and automation systems, providing flexibility in circuit design and operational efficiency.
