Web11 de dez. de 2024 · In a general relay, the contacts close while the coil is supplied with current and return to open state when the coil is cut off from the current supply. These general relays are also called single stable type relays. . In a latching relay, inputting a pulse signal to the coil causes the contacts to close and remain at that … Web15 de ago. de 2024 · 1. From a safety perspective, its unclear. As you alluded to, the DC ratings are often much lower than the respective AC ratings. You're probably fine at less than 1 A for a one-off project. If the project will require any type of safety certification (i.e. UL), you are better off getting a relay with the correct rating.
