Abstract
The invention relates to a semi-fabricated switching device comprising a semiconductor element and a housing comprising a spring system with a ring-shaped washer laterally surrounding the semiconductor element for clamping the semiconductor element between two pole pieces. The washer is deflectable between the pole pieces by a first deflection element, which contacts the washer in a first contact area on a first side, and by a second deflection element, which contacts the washer in a second contact area on a second side. The first contact area is displaced to the second contact area. The first and second deflection element can deflect the washer such that in clamped condition an electrical contact is achievable between the pole pieces and the semiconductor element.
