Abstract

A hand-controlled breaker comprises a housing (1), a control button (12), and a control bar (21). Two rods (15, 15') are mounted so as to pivot inside the control button, and extend downwardly outside the control button towards the cavity of said housing. Each rod comprises an oblique supporting surface (17, 17') oriented in an inward and downward position, and a second lower oblique supporting surface (19, 19') oriented in an inward and upward position. The four supporting surfaces surround and maintain a cylindrical part (20) coupled to an upper portion of the bar (21). The rods each further comprise an oblique supporting surface (58, 58') outwardly and upwardly directed to against a lower edge of a bore (10) of an upper portion (4) of the housing.
