<p>The contact system is mounted in a case, filled with protective gas, with a magnetic base plate and a non-magnetcover. A fixed contact is in the form of a contact pin inserted into and insulated from the base plate. The movable contact consists of a meander-shaped armature supporting spring connected to the base plate, whose middle part serves as contact spring(s). The armature and current carrying springs above it are mounted on the support spring (6). The armature supporting spring is provided at both ends with stops (8, 10, 9, 14) bent at a right angle and fastened to the base plate (1). Preferably the stops and the armature support spring are made in one piece.</p> |
