Latchströmmen

Latchströmmen is a Swedish term that translates to "latch current" or "holding current" in English. It refers to the minimum current required to maintain the conductive state of a latching relay or a similar bistable electronic device. Once a latching device has been activated or switched on, it will remain in its current state even if the activating signal is removed. However, a certain level of continuous current, the latchströmmen, is necessary to keep it in that state.

If the current drops below the latchströmmen, the device will revert to its default or off state. This characteristic is crucial for power-sensitive applications, as it allows for the device to be switched on with a brief pulse of current and then remain active with minimal ongoing power consumption. This is in contrast to non-latching devices that require a continuous signal to maintain their state. Understanding and specifying the latchströmmen is important for engineers designing circuits that utilize latching mechanisms, ensuring reliable operation and efficient power management. The exact value of latchströmmen varies significantly depending on the specific type and design of the latching component.
