The present disclosure provides a touch panel which at least comprises a sensing area, a conductive wire area, and earthing lines. The conductive wire area surrounds the sensing area and is electrically connected to the sensing area, and the conductive wire area comprises a first conductive wire area and a second conductive wire area. The earthing lines are set between the first conductive wire area and the second conductive wire area. The touch panel can efficiently shield signal crosstalk between the first conductive wire area and the second conductive wire area by setting the earthing lines between the first conductive wire area and the second conductive wire area, thereby reducing the influence of signal crosstalk on efficiency of the touch panel.

The present invention relates to a circuit-breaking device for low-voltage systems with a control mechanism that has improved characteristics of compact size and reliability. The circuit-breaking device according to the invention comprises an outer housing containing, for each pole, at least one fixed contact and at least one moving contact suitable for being mutually coupled and uncoupled. The device also comprises a control mechanism comprising a supporting frame that supports a kinematic chain operatively connected to the moving contact so as to enable the latter to be coupled to or uncoupled from the fixed contact. The supporting frame comprises a pair of sides connected by means of a first transverse connecting portion and by further connection means that define a further transverse connecting portion in a different position from that of the first transverse connecting portion.

Apparatus and systems provide processing capabilities and power-line networking capabilities. An in-wall computing device has a power connector for receiving an Alternating Current (AC) signal from a power source and a housing that is sized for installation into an electrical wall box. The device may have internal data injection circuitry for injecting data into the AC signal or may have internal data receiving circuitry for extracting data from the AC signal. A system includes at least two in-wall computing devices, each having a power connector for receiving an AC signal from a power source. A first device has a user input interface and internal data injection circuitry for transmitting user input data to a second device over the AC signal. The second device has internal data receiving circuitry for extracting the user input data and controlling peripherals attached to peripheral ports of the device according to the data.

An electrical switch includes a dielectric casing, first and second terminal units, and an actuating unit. The dielectric casing includes a cover and a, mounting seat. The mounting seat is disposed in and attached to the cover. Each of front and rear ends of the mounting seat is formed with a notch. Each of the first and second terminal units extends into the cover through the notch in a respective one of the front and rear ends of the mounting seat. The actuating unit extends into and is coupled to the cover, and is operable so as to selectively connect and disconnect the first terminal unit to and from the second terminal unit.

A lid-mounted monitor includes a touch panel mounted on a screen of a liquid crystal display, for inputting information when touched, a lid mountably and dismountably disposed on the touch panel, the lid including a small window formed therein, by way of which the screen of the display can be partially seen while the lid is mounted to the touch panel, and an operation unit by way of which the touch panel can be touched, a detecting unit for determining whether the lid is mounted or dismounted to or from the touch panel, and a control unit for, when the lid is dismounted from the touch panel, displaying information on the entire screen of the display and accepting information corresponding to positions where the touch panel can be touched, and for, when the lid is mounted to the touch panel, displaying information on a part of the screen of the display corresponding to the small window and accepting information corresponding to positions where the touch panel can be touched.
摘要:
Disclosed is a switch, which comprises an insulative plastic case having a cavity formed therein, a metal cover joined to the case to cover over the cavity, and a switching contact section contained in the cavity. In this switch, a surface of the cover opposed to the case has an insulative film formed on at least a region of the surface facing to the cavity. The switch can prevent an externally-originated static elasticity from adversely affecting on the switching contact section to protect a circuit section of a device connected to the switching contact section.

The present invention disclosures a two-position three-wire switch comprising a shell and two three-wire switches located in the shell. Each three-wire is composed of a pair of static contactors, a U-moving contactor, a common carriage, a middle separator plate and a toggle lever which are provided in the shell; said static contactor and common carriage are fixed at the bottom of shell; a pair of static contactors is provided on both sides of common carriage; a V-sustainer is provided at each end of said common carriage; U-moving contactor is provided located on the V-sustainer and two contacts on the outside of U-moving contactor can be connected or disconnected with the contact on a pair of static contactors; a spring is provided in U-channel of said U-moving contactor; a middle separator plate is covered over said static contactor, moving contactor and fixing carriage; said toggle lever, passing through the cover of the shell, and middle separator place, is connected with the spring in U-channel of the moving contactor.
摘要:
An inhibitor switch having a construction that facilitates fabrication by disposing a bearing surface made of a metal plate so as to be exposed at a bottom surface of a shaft hole to which a shaft of a movable plate is pivotably fitted, and having fixed contact plates formed in a pole plate by insertion molding. The movable plate has movable contacts, which are brought into contact with the fixed contact plates. A movable arm is secured to the movable plate. A case supports pivotably the movable plate together with the pole plate. The bearing surface made of a metal plate is disposed so as to be exposed at the bottom surface of the shaft hole to which the shaft of the movable plate is pivotably fitted. The bearing surface can be integral with one of the fixed contact plates.
