A dial shift lever device for a vehicle may be provided that includes: a dial knob which is rotatable from a predetermined reference position by a user's operation for changing a shift stage; a button driving part which comprises a plurality of buttons disposed circumferentially in a receiving recess formed in a lower portion of the dial knob and generates a signal for selecting the shift stage as at least one of the plurality of buttons is pressed by rotation of the dial knob; and a guide assembly which is coupled to the lower portion of the dial knob and locks the rotation of the dial knob or releases the lock of the rotation of the dial knob.

A toggle lever connection for connecting at least two toggle levers is disclosed. The toggle levers each include two grooves arranged opposite each other. The toggle lever connection includes a frame and a slider with one hook per toggle lever. The frame and the slider run into each other and can be displaced in relation to each other between a first, open position, in which the toggle lever connection can be placed onto the at least two toggle levers or removed therefrom, and a second, closed position, in which the hooks grip into the grooves of the at least two toggle levers, thereby locking the toggle lever connection to the toggle levers.

A computer mouse is provided to make the mouse button easily reachable without being susceptible to misclick. The computer mouse may include an electronic circuit configured to implement operations of the computer mouse. The computer mouse may include a housing enclosing the electronic circuit. The housing may include an opening on one side of the housing and a switch on the side of the housing. The computer mouse may include a magnetically active lever attached to the housing through the opening on the side of the housing. The magnetically active lever may be configured to actuate the switch on the side of the housing to interact with the electronic circuit to provide input to a computing device. The magnetically active lever may be removable from the housing and replaced with a magnetically active lever of a different size or shape.

A switch has a base, an operation unit disposed above the base and moving in a contacting-separating direction with respect to the base in response to an external force, a pair of link members configured to guide movement of the operation unit in the contacting-separating direction, and a coupling portion configured to turnably couple the pair of link members to each other. Each of the pair of link members each includes a coupling-portion-side supported portion supported on one of the base and the operation unit and an end-side supported portion supported on the other of the base and the operation unit. One of the base and the operation unit on which the coupling-portion-side supported portion is supported includes a wall surface provided with a movement space.

A closed door operation racking device is provided for racking a circuit breaker to and from a power bus from outside of a housing of a motor control center unit. The racking device includes a racking operator assembly and a push-button interlock assembly. The racking operator is configured to rack-in the electrical device and connect the stabs to a power bus in a connected position and to rack-out the electrical device and disconnect the stabs from the power bus in a disconnected position. The push-button interlock assembly prevents the operation of the racking operator under certain conditions, and includes a spring-loaded locker assembly and a spring-loaded push-button operator assembly. A push-button operator of the push-button operator assembly is depressed to disengage the locker assembly from the racking operator to allow operation of the racking operator.

A dial shift lever device for a vehicle may be provided that includes: a dial knob which is rotatable from a predetermined reference position by a user's operation for changing a shift stage; a button driving part which comprises a plurality of buttons disposed circumferentially in a receiving recess formed in a lower portion of the dial knob and generates a signal for selecting the shift stage as at least one of the plurality of buttons is pressed by rotation of the dial knob; and a guide assembly which is coupled to the lower portion of the dial knob and locks the rotation of the dial knob or releases the lock of the rotation of the dial knob.

The invention provides an electric drill including a bracket with a handle, a drill rod, a motor assembly, and a switch assembly. The switch assembly includes a first micro switch configured to activate or deactivate the motor assembly, a switch pivotably mounted on the handle through a pivot and cooperating with the first micro switch, and a self-locking button engaged with the switch and configured as: when the self-locking button is in a first state, the self-locking button abuts against the switch to prevent the switch from rotating around the pivot; when the self-locking button is in a second state, the self-locking button is disengaged with the switch, and the switch can rotate around the pivot.

An improved mechanical interlock including one or more features to facilitate a more robust design, easier assembly, and/or enhanced capabilities. For example, the mechanical interlock may include an interlock latch operatively associated with an external handle assembly and an internal connector. The interlock latch being directly coupled to a shaft coupled to the handle assembly, thus providing an improved and more robust latching mechanism. The mechanical interlock may also include one or more keys (e.g., a Poke-Yoke feature) to facilitate easier assembly and/or to prevent human errors caused by improper assembly. The mechanical interlock may also include an integrated magnetic switch and monitoring system to ensure that accurate location of the handle assembly is known.

Disclosed herein is a magnetic trip device. The magnetic trip device maintains a failure state indication through a latch, a lever, and a trip bar which are provided in the magnetic trip device and thus a switching part can be operated or maintained with a more simplified structure.

A switch has a base, an operation unit disposed above the base and moving in a contacting-separating direction with respect to the base in response to an external force, a pair of link members configured to guide movement of the operation unit in the contacting-separating direction, and a coupling portion configured to turnably couple the pair of link members to each other. Each of the pair of link members each includes a coupling-portion-side supported portion supported on one of the base and the operation unit and an end-side supported portion supported on the other of the base and the operation unit. One of the base and the operation unit on which the coupling-portion-side supported portion is supported includes a wall surface provided with a movement space.
