Electrical apparatus, has fixing unit with spring blades positioned in constrained state between covering plate and base to support against blades by elastic expansion and maintain them by friction integrated to each other

摘要

The apparatus has a base (120) with an interrupter to retrieve on a rear side of a covering plate (110). A fixing unit integrates the covering plate to the base. The fixing unit has a set of spring blades (130) positioned in a constrained state between the covering plate and the base to support against the spring blades by elastic expansion and to maintain them by friction integrated to each other.
