Animation of an impulse relay: Upon activation, the switching contact will always take a different position (open or close)
A teleruptor, impulse relay or remote switch is a remote assisted relay relay, with one or more switching contacts changing at each current pulse. This position is retained to a next pulse.
An impulse relay offers advantages over regular monostable relays in circuits in which the relay must remain in the same position for a long time, and where the lowest possible current consumption is important. The increased contact pressure that is independent of the energization and thus provides greater reliability is another advantage. The independence of power failure can also be an advantage.
OperationA teleruptor operates according to an electromagnetic principle. The mechanism has been constructed so that the switching contact, at each short current pulse, changes through the built-in coil. The relay maintains that position until the next pulse. Holding the anchor in one of two positions can be controlled by mechanical, or permanent magnetic means. Application
The pulse relay is used where remote remotely should be operated from multiple locations. In the lighting world, it is often used to remotely enable remote control by pressing pushbutton control, or even to diminish it stepwise. It can advantageously replace a crossover of any size by material saving. Also see
