A key structure includes a keycap, a pedestal and an elastic element. The keycap includes a main body and a coupling shaft. The pedestal includes a key slot. The key slot has an upper part and a lower part. The coupling shaft is penetrated through the upper part of the key slot and movable within the key slot upwardly or downwardly. The elastic element is installed in the lower part of the key slot. After an external force applied to the keycap is released, the elastic element is elastically restored, so that the keycap is returned to an original position. At the same time, the buffering elements in the key slot interfere with the coupling shaft. Consequently, an ascending speed of the keycap is reduced, and a click sound generated from the collision between keycap and the pedestal is reduced.

A keyboard device with a display panel including a base, a scissors feet assembly movably disposed on the base, an elastic member disposed on the base, a display panel supported by the scissors feet assembly and the elastic member, and multiple light transmittance keycaps disposed on the display panel is provided. The display panel has multiple display surfaces, multiple hollow portions, and multiple elastic portions. Each of the display surfaces is surrounded by the hollow portions, and is suspended between the hollow portions by the elastic portions. The light transmittance keycaps respectively and correspondingly cover the display surfaces.

What is presented is a key module (100) comprising an actuation element (105) comprising a cam nose (135), wherein the actuation element (105) is supported to be movable along a movement axis (200) in a housing element (130, 110). Furthermore, the key module (100) comprises a contactor unit (115) with a contact nose (140) movable in the direction of the movement axis (200) and transverse to the direction of the movement axis (200). Also, the key module (100) comprises a contact element (120) formed and arranged for establishing electric contact with the contact nose (140). Moreover, the key module (100) comprises the housing element (130, 110) for accommodating the contact element (120), the contactor unit (115) and the actuation element (105), wherein the actuation element (105) and/or the cam nose (135) comprises at least one constructive element (400) formed to deflect the contact nose (140) from a rest position adjacent to the contact element (120) in the direction along and/or transverse to the movement axis (200) upon a defined movement of the actuation element (105), then abruptly release it so that the movable contact nose (140) returns to the rest position and strikes the contact element (120) and/or the housing element (130, 110), wherein electric contact with the contact element (120) is established and acoustic noise is produced.

An inspection station is capable of being used under harsh conditions. The inspection station includes switch elements to which the inspection station is responsive for generating a predetermined control signal in response to actuation of a switch element. A fluid tight sealing element isolates an interior of the inspection station from an outside of the inspection station, the sealing element including one or more flexible button areas at the locations of the switch elements to provide access from the outside of the inspection station to actuate the switch elements located in the interior of the sealing element.

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 electronic device is provided. The electronic device includes a frame, a signal trigger fixed inside the frame, and a button penetrating the frame. The button includes a button post, an elastic cushion, and a button cap. The button post penetrates the frame to be adjacent to the signal trigger. The elastic cushion is fixed to an end of the button post away from the signal trigger. The button cap is fixedly connected to a side of the elastic cushion away from the button post. The elastic cushion is connected between the button post and the button cap, and the button cap can move relative to the button post due to elastic deformation of the elastic cushion.

A control device which allows an operator/user to follow the user's anatomical movement by following natural hand rotation, includes two independent detection sensors or sensor portions embedded in two different parts of the device, one in a fixed part and one in a mobile or rotative part, with resistance to mutual disturbance between the two. The device includes a knob portion rotatable about an axis of rotation, at least one sensor configured to sense a rotational position of the knob in relation to the axis of rotation, circuitry adapted to at least provide electrical power to the rotative knob portion, circuitry adapted to transmit the sensed rotational position of the knob, and a base portion rotatably coupled to the knob portion.

A magnetic electrical switch apparatus includes: a switch assembly that includes: a switch body housing including a stationary contact; a shaft configured to move relative to the switch body housing, the shaft including: a moveable contact; and a first magnet; and a movable support member including a second magnet. The moveable contact and the first magnet are configured to move with the shaft. Moving the movable support member moves the second magnet relative to the first magnet, and a magnetic interaction between the second magnet and the first magnet moves the moveable contact relative to the stationary contact to thereby change a state of the switch assembly.

An inspection station is capable of being used under harsh conditions. The inspection station includes switch elements to which the inspection station is responsive for generating a predetermined control signal in response to actuation of a switch element.

Example of backlit switches are described. In an example, a backlit switch includes a printed circuit board (PCB) and a dome-type button coupled to the PCB. The dome-type button has a light transmitting portion. A light source is mounted on a first side of the PCB, and a tact switch is mounted on a second side of the PCB that is opposite to the first side. Further, a projection is provided to trigger the tact switch, in response to pressing of the dome-type button.
