Abstract: The present disclosure relates to a structure of a crossbar for a manual motor starter, and particularly, to a structure of a crossbar for a manual motor starter in which a function of an auxiliary lever is performed by a crossbar to thus reduce the number of components and an operational error. The structure of a crossbar for a manual motor starter (MMS) including a crossbar connected to an operating mechanism and an auxiliary contact lever operating an auxiliary contact, wherein a pressing unit is formed in the crossbar to operate the auxiliary contact lever upwardly.

Abstract: A switch (1) for roof lights (2) has: a supporting frame (3); a push-button (7) slidably mounted on the frame (3); a printed circuit, which is associated to the frame (3) and defines two operative positions for a lamp-bulb; and an actuator (13), which is set between the push-button (7) and the printed circuit (8) and is moved by the push-button (7) between the two operative positions; the actuator (13) being provided with a rolling element (18), which can roll on the printed circuit (8) between the two operative positions, and an motion-imparting arm (15), which supports the rolling element (18) and is actuated by the push-button (7) for moving the rolling element (18) itself between the operative positions.

Abstract: A safety press-button switch includes a linkage formed of a lever and a switching rod pivoted together, and a press-button cap having a push rod and a hook arm respectively aimed at the switching rod and a positioning rod of the lever and adapted to force the lever to shift a bimetal plate from OFF position to ON position and to hold the lever in position after the bimetal plate switched on, the positioning rod of the lever being forced away from the hook arm by the deformation force of the bimetal plate for enabling the bimetal plate to trip off automatically upon an overload.
