Swiveling lever driving mechanism for electrical protection apparatus actuating mechanism of remote control block, has spring forming unit storing energy during actuation so that arm end takes two positions for each position of fixing unit

摘要

The mechanism (150) has a fixing unit (153) for fixing an arm to an actuator. An arm (151) swivels around an axis (152). Another arm (160) includes an end coupled with an integration unit (155) of the former arm. Detachable coupling units are coupled to a lever. A spring forming unit stores energy during actuation so that another end (161) of the latter arm takes two positions for each position of the fixing unit. The latter arm includes two parts sliding with each other. One of the parts is coupled by the spring forming unit to an end of the other part. An independent claim is also included for an actuation mechanism for an electrical appliance including a driving mechanism.
