An input device including a housing and a depressible key plate disposed thereon. The key plate includes a front user-accessible portion, a pivot support portion, and a rear portion. A shaft is disposed in the pivot support portion, where the key plate rotates with respect to the shaft. A force sensor is disposed in the housing and in contact with a bottom surface of the front portion of the key plate, and activates in response to receiving a predetermined force by the bottom surface of the front portion of the key plate. The depressible key plate depresses in response to receiving a predetermined depression force on the top surface. A biasing mechanism is disposed in the housing and in contact with the bottom surface of the rear portion of the key plate to provide an upward force tuned to be substantially equal to the predetermined depression force.

Provided is a switch that can reliably bring contacts into contact with each other with a small load, and can be prevented from malfunctioning. A switch is provided with a plunger, a lower torsion spring in which a biasing direction changes according to the movement of the plunger. The lower torsion spring biases the plunger in an opposite direction to a returning direction when the plunger is in the operation position, and biases the plunger in a direction different from the opposite direction to the returning direction when the plunger is in the reference position.

A backlight module for a lighting keyboard including at least two heat-dissipating keys comprises a reflective layer, a light guide panel and a shielding sheet and has at least two penetration channels. The reflective layer, the light guide panel and the shielding sheet are stacked up and down. The penetration channels symmetrically correspond to the heat-dissipating keys respectively and penetrate the reflective layer, the light guide panel and the shielding sheet. The penetration channels are respectively provided with one light-reducing pattern at their periphery for blocking light. At least two diffusion patterns are arranged adjacent to the light-reducing patterns for guiding light to illuminate the heat-dissipating keys. The light-reducing patterns and the diffusion patterns form at least two heat-reducing optical pattern groups respectively. The heat-reducing optical pattern groups respectively corresponding to the heat-dissipating keys have identical patterns.

An electronic device has a concealed external electrical connector that may be activated by a pin of a mating connector. When the pin applies a force to an electrically conductive and flexible region of an exterior housing of an electronic device the electrically conductive region deflects inwards coupling to a contact within the electronic device. A bi-directional communications path is then established from the pin of the connector, through the conductive portion of the housing, to the contact and to circuitry within the housing of the electronic device.

A circuit breaker includes an electrically insulative case including a first end and a second end opposite the first end. The circuit breaker further includes an end cover selectively installable on both the first and second ends of the electrically insulative case. The end cover includes a wall defining at least one opening for receiving a removable shield, a first end connectable to the electrically insulative case first end, and a second end connectable to the electrically insulative case second end.

An input device includes a touch panel incorporating a switch electrode region, and an actuator. The switch electrode region includes a switch electrode and a ground electrode disposed side by side with the switch electrode. The actuator includes a push button having an operation surface, an elastic body, a conductor, and a facing surface. The conductor faces the switch electrode region and is separated from the switch and ground electrodes. The conductor moves in line with a press put on the push button such that a capacitance value between the conductor and each of the switch and ground electrodes changes in response to a distance between the conductor and the switch electrode.

A multidirectional input device is capable of performing a tilting operation and a pressing operation. The device includes a strain inducing body that includes a cylindrical portion and one or more deformable portions provided on an outer side of the cylindrical portion, a plunger provided inside of the cylindrical portion of the strain inducing body, a strain detecting element provided at the deformable portion of the strain inducing body, a substrate provided on a bottom portion of the cylindrical portion of the strain inducing body, and an elastic member provided between the substrate and a bottom portion of the plunger. The strain inducing body is fixed to a device main body at an outer end portion of the deformable portion. The substrate is fixed to the strain inducing body.

Disclosed is a molded case circuit breaker including a case configured to accommodate an element for trip, an upper cover detachable attached to the case, a dial configured to include a fixing plate, which is provided to protrude along an outer circumference surface thereof, and a first stopper disposed under the fixing plate, a crossbar moved by the dial, a first dial fitting hole provided in the upper cover for the dial to be fitted into the first dial fitting hole, and a dial rotation adjusting unit provided in the first dial fitting hole and fitted between the fixing plate and the first stopper to guide a rotation of the dial, the dial rotation adjusting unit including a plurality of fitting grooves arranged at certain intervals. The first stopper is fitted into and fixed to the plurality of fitting grooves according to the rotation of the dial.

A circuit breaker includes a main body case, an operating handle having a base portion and a knob portion protruding outwardly through a handle window frame opened in a cover of the main body case; a first shutter arranged between the base portion of the operating handle and the handle window frame, and disposed on the base portion, the first shutter being formed with a loose-fit hole to loosely fit the knob portion therethrough; and a second shutter disposed on the first shutter to move along with the knob portion. At ON and OFF positions of the operating handle, the first shutter extends beyond a front/rear edge of the handle window frame in a front-back direction to close the handle window frame, and the second shutter extends beyond a front/rear edge of the loose-fit hole in the front-back direction to close the loose-fit hole.
