Is there a relay with a function to hold the contact even if the coil voltage of the relay is turned off?

ID: FAQE10007E



A latching relay can maintain the contact even if the voltage applied to the relay coil is turned off.
Latching relays can be either single-winding or double-winding.


Latching relay
See below for single and double winding latching relays.

Please select a relay based on the following model configurations.

Quick tips

We have prepared a technical support page dedicated to high-capacity relays that explains in detail "I don't know" when using high-current, high-voltage PCB power relays, such as back EMF voltage (Zener diode and varistor) of the coil, holding voltage application circuit, recommended conditions for high-current substrate flow solder, the influence of magnetic fields, and precautions when connecting in series and parallel. Please also use this as well.
