Abstract:
1. A switchgear, comprising: a relay with a magnet frame consisting of a coil former and a coaxial coil with a yoke, the coil having at least one coil terminal pin extending there from configured to supply an operating voltage to the coil; a flexible printed-circuit board provided with at least one electronic component, the flexible printed-circuit board having a substantially U-shape with substantially parallel ends extending in separate planes, each of the ends extending in a direction of extension of the coil terminal pin and at least one of the ends being electrically connected to the coil terminal pin to form a supplementary electrical circuit, and a relay housing cover positioned over the relay and the flexible printed-circuit board, wherein, the flexible printed-circuit board is sized such that, when viewed in a longitudinal direction of the magnet frame, it is disposed between an armature and a contact element of the relay; the relay is mounted in a base unit and the ends of the flexible printed-circuit board are arranged in the base unit; the electronic component is connected in parallel with the coil; and, the supplementary electrical circuit is an electrical protective circuit or an electrical display circuit.
