A mouse with a removable button switch includes: a release unit, including a bearer mounted on a circuit board of the mouse; a press-fixing and ejection means provided with a press-fixing part and an ejection part; and a press-fixing means, the press-fixing means and the press-fixing and ejection means being oppositely disposed on both sides of the bearer, and the press-fixing means being provided with the press-fixing part. In the mouse with the removable button switch in the present invention, because the button switch is not fixed on the circuit board of the mouse in a welding manner, when the button switch is faulty or a different hand feeling is required, the button switch can be conveniently replaced without causing damage to the mouse.

Disclosed is refrigerator including a holder terminal unit provided in a main body of the refrigerator; and a shelf terminal unit provided in a shelf installed in the main body, wherein the holder terminal unit includes a holder installed at an inner rear wall of the main body and having an opening which is opened toward a front side of the refrigerator; a holder side terminal provided to correspond to a shelf side terminal of the shelf terminal unit and movable in forward and backward directions within the holder; and an elastic member provided between the holder and the holder side terminal and configured to elastically support the holder side terminal, and wherein the holder side terminal is pressurized by the shelf side terminal which is inserted into the holder through the opening and moved backwardly, while maintaining an elastic contact with the shelf side terminal by the elastic member.

A component for a high-voltage electric system of a vehicle includes a body having a circular cross section; an electrical device encapsulated within the body; a first electrically conductive contact area arranged circumferentially on the body and configured to form a first electrical connection to the electrical device; a second electrically conductive contact area arranged circumferentially on the body and configured to form a second electrical connection to the electric device, the second electrically conductive contact area being separated from the first electrically conductive contact area in the axial direction of the body; a cap attached to an end portion of the body; and a fastening mechanism configured to secure the component in a socket.

A switching apparatus for electric power distribution grids including: a withdrawable first switching unit having one or more first electric poles; a withdrawable second switching unit having one or more second electric poles and electrically connected ins series with said first switching unit; wherein said second switching unit includes an emergency control arrangement activatable by a user to make said second switching unit to carry out an opening manoeuvre.

A plug-in circuit breaker that includes a circuit breaker housing with a limiting hole and a opening and closing button. The circuit breaker further includes a locking member rotatably arranged inside the circuit breaker housing with an upper portion close to the limiting hole provided with a locking protrusion fitting. A lower portion of the circuit breaker housing is provided with a locking driving surface fitting with the opening and closing button. When the limiting hole is not shielded, the opening and closing button jacks up the locking driving surface to enable the locking protrusion to extend out of the limiting hole. The plug-in circuit breaker is closed when the limiting hole is shielded, so that the locking protrusion cannot extend out of the limiting hole. The locking driving surface limits the opening and closing button, so that the opening and closing button cannot press to the destined position.

A trigger switch includes: a trigger that receives a pushing operation; a shaft member that supports the trigger on one end side thereof; and a housing in which a through hole is opened through which the other end side of the shaft member passes. The shaft member moves inside the housing due to the pushing operation on the trigger. The trigger switch includes a covering member that covers the shaft member in a circumferential direction, has its inside sealed, and is expandable and contractible in an axial direction. The covering member has one end side attached to an outer periphery of the shaft member and has the other end side attached to a periphery of the through hole of the housing.

A first connector including a pair of male terminals of which axial directions of rod-like bodies having a circumferential surface are aligned in the same direction and which is arranged at an interval, a conductive coupling member which couples one ends of the respective male terminals in the axial direction to each other, and a first housing which includes a male terminal housing chamber for each male terminal and a holding mechanism which holds the coupling member the male terminal includes a rod-like body having a male terminal fitting portion to be inserted and fitted into the female terminal on the other end and a spherical turning fulcrum body which is provided at the one end and enables the turn with respect to the coupling member in the male terminal housing chamber about the one end as a fulcrum.

An accessory wire retention assembly is for an electrical switching apparatus, such as a circuit breaker. The circuit breaker comprises a housing, separable contacts and an accessory enclosed by the housing, an operating mechanism for opening and closing the separable contacts, and a number of wires adapted to be electrically connected to the accessory. The wires extend from the interior of the housing through an aperture to the exterior. The accessory wire retention assembly includes an insert which cooperates with the housing and to establish a predetermined position of the wires with respect to the accessory and the aperture, and a fastening mechanism which fastens the wires to the insert to maintain the wires in the predetermined position.

An input device including a switch connector having a plurality of electrical terminals fixedly mounted to a circuit board. The input device including a switch assembly magnetically coupled to the switch connector in a removable manner. The switch assembly including a switch adapter having a plurality of contact elements in engagement with the plurality of electrical terminals of the switch connector, and a switch fitted to the switch adapter with a plurality of leads of the switch electrically connected to the plurality of contact elements of the switch adapter. The switch adapter being between the switch connector and the switch. The input device including a magnetic catch arrangement having a first catch unit at the circuit board and a second catch unit at the switch adapter which coact with each other to magnetically couple the switch assembly to the switch connector. A corresponding switch assembly thereof and a computer mouse.
