Only a short switching pulse is required to make the K-RP bistable relay from HENGSTLER reliably switch over. This means that, even in the event of a power outage, the relay is always in a clearly defined, safe switching position. The special H-armature construction means that extremely high shock and vibration resistance can be achieved. A manual switch is available in a number of colours to suit customer preference to enable the switching state to be manually operated.
