Current relays and power impulse switch

Current relays and power impulse switch

The peculiarity of current relays is that they switch from a predetermined current flow. Because of their accuracy, electronic current relays are not only used in measurement and control systems, but also circuit monitoring. Impulse switches, however, are electromagnetically operated. Impulse switches are installed in larger buildings when numerous switches are used to control a light group. Here, a current pulse activates, switches and maintains the relay in position. Only after a renewed switching command it changes its switching state.
