Abstract

Un dispositivo compatto di comando manuale per interruttori di manovra comprendente una maniglia montabile su una parete di una apparecchiatura contenente un interruttore azionabile dalla rotazione di un'asta dotata di elementi sporgenti che è vincolabile amovibilmente ad una porzione interna della maniglia ed è associata girevolmente ad un piatto di base, l'asta essendo ruotabile tra una posizione disinserita di contatti elettrici interni in cui è svincolabile dalla maniglia ad una posizione inserita dei contatti elettrici interni ove è bloccata alla maniglia. Entro il corpo della maniglia è ricavata una apertura atta a ricevere l'asta e gli elementi sporgenti, sul piatto di base è posizionato un elemento elastico allineabile all'apertura e alle estensioni ricavate nella maniglia in una posizione del piatto di base e sovrapponibile in impegno all'asta e agli elementi sporgenti contenuti nelle estensioni in una seconda posizione. Il corpo di base è incavato e richiudibile da un elemento di chiusura recante anch'esso una apertura per il passaggio dell'asta con elementi sporgenti.
