The present invention relates to a molded case circuit breaker, in which a locking member is formed at an inner side of a lever and an anti-rotation member is formed at an upper like. Accordingly, the locking member can be brought into contact with the anti-rotation member even though a handle is rotated to an OFF position even in a fused state between a fixed contactor and a movable contactor, thereby preventing a rotation of the handle to the OFF position.

A switch device includes a substrate including stationary contacts arranged side by side, a contact including linear parts having elasticity and movable contacts, a housing holding a base of the contact and including beams having elasticity each of which is disposed above the corresponding one of the linear parts, and a slider disposed above the housing. A first pressing part is formed on a lower face of each of the beams, and a pressed part is formed on an upper face thereof. Second pressing parts are formed on the slider. When the slider moves in the front-back direction in conjunction with the operation of an operation knob, the second pressing parts press the pressed parts to bend the beams downward, the first pressing parts press the linear parts to bend the linear parts downward, and the movable contacts come into contact with the stationary contacts.

Trigger activated tools are provided that have one or more activation lockouts. The activation lockouts include electrical resets, variable position lockouts, mechanical lockouts, shield lockouts, and any combinations thereof.

A switching device and apparatus for switching on suddenly has an actuating mechanism element operatively connected to a latching mechanism by a transmission mechanism, The latching mechanism operates a switching lever through a further transmission mechanism. A contact assembly has a fixed switching piece facing a moveable switching piece that is guided in a contact slide. In the latching mechanism, a lever is arranged in operative connection with a locking part that is operatively connected to a transmission element which acts on the moveable switching piece.

A semiconductor device includes a HEMT and a diode. The HEMT includes: a substrate having a GaN layer as a channel layer generating a two-dimensional electron gas and an AlGaN layer as a barrier layer on the GaN layer; a source electrode on the AlGaN layer ohmic contacting the AlGaN layer; a drain electrode on the AlGaN layer apart from the source electrode and ohmic contacting the AlGaN layer; an inter-layer insulating film on the AlGaN layer between the source electrode and the drain electrode; and a gate electrode on the inter-layer insulating film. The substrate includes an active layer region generating the two dimensional electron gas in the GaN layer. The diode includes an anode electrically connected to the gate electrode and a cathode electrically connected to the drain electrode.

A circuit breaker includes a housing having a channel formed therein, the channel being defined by at least one side wall having a detent formed therein, a circuit breaker mechanism, a switch handle configured to toggle the circuit breaker, and an actuator module adapted to move the switch handle from the off position to the on position. The module includes a flexible portion having a protrusion formed thereon, the protrusion being sized, shaped and located to engage the detent when the module is mounted within the channel. The module also includes a locking clip moveable from an unlocked position, in which flexing of the at least one flexible portion is permitted, and a locked position, in which flexing of the at least one flexible portion is limited or prevented, such that when the module is mounted within the channel, removal of the module is inhibited.

A switch (30) for a hand-held power tool (10) or as a component of a hand-held power tool (10), which has an electric drive motor (16) that can be switched by the switch (30). The switch (30) has a switch housing (33) with a switch chamber (35) in which a switch actuator (75) that can be moved between at least two switch positions (ML, MR) is arranged in order to actuate an electric switch element, said switch actuator being kinetically coupled, by means of a transmission element (70), to a switch (30) actuation element (32), which is arranged outside the switch housing (33) and can be moved between at least two actuation positions (R, L), wherein the transmission element (70) passes through a through-opening (54) on a wall of the switch housing (33) such that the switch actuator (75) can be moved by moving the actuation element (32) in order to actuate the switch element (24). A rotary bearing (77) is arranged in the through-opening (54), the transmission element (70) being rotatably mounted on the rotary bearing about a rotational axis (D).
