Latching relays maintain their contact position after receiving a pulse, requiring a second pulse to switch back. This bistable operation reduces continuous power consumption and enhances energy efficiency. Using mechanical or magnetic locking mechanisms, these relays provide stable switching in applications where state retention is critical. They are widely used in railway and industrial systems where reliable position memory and minimal energy usage are required.
Plug-in bistable railway relay with eight change-over contacts, for reliable switching of very low currents (1 mA @5 VDC) up to currents of 10A @ 110VDC. The contacts remain in the last powered position, the position is clearly
