Abstract: A remainder electric power distributing device of a computer for distributing the remainder electric power supplied form the power supply of the computer to auxiliary electronic devices includes at least one power jack and a connecting means. The power jack is electrically connected to the power supply of the computer and has at least one connecting interface exposed on the computer, such that another auxiliary electronic devices disposed outside the computer are electrically connected to the power jack and further share the electric power supplied from the power supply. The connecting means is used for installing the power jack to the computer.

Abstract: A complementary fan rotational speed control method and apparatus for simultaneously monitoring the rotation speeds of two or more fans includes a control unit to output pulse width modulation (PWM) control power supply to activate operation of a first fan and a second fan. The first and the second fan deliver rotation pulse signals to the control unit. When the control unit detects the rotation speed of either the first or second fan decreases, it actuates other fan to increase rotation speed and issues a warning signal to secure cooling effect and increase the service life of the fans.

Abstract: An arc discharge protection apparatus to prevent arc discharge from occurring in a high voltage output zone caused by abnormal conditions includes an electrode plate to absorb high voltage arc discharge signals released by a voltage boosting unit in the high voltage output zone. A voltage switch unit receives the high voltage arc discharge signals absorbed by the electrode plate and transforms to low voltage arc discharge signals. A rectification unit receives and rectifies the low voltage arc discharge signals and outputs an arc hybrid wave. A trigger unit detects the arc hybrid wave and outputs a trigger signal to stop operation of the control unit or driving unit, thereby prevents arc discharge from causing damage to the surrounding elements resulting from accumulation of heat or sparks.

Abstract: A current/charge leakage balancing device is used to balance the current/charge leakage that occurs between the display and the backlight module due to the parasitic capacitance effects. The current that respectively flows through each lamp is thereby balanced, which enables to maintain uniform lamp sources and provides uniform brightness of the display panel.

Abstract: This invention discloses a rocker switch which provides a reliable movement and a heat-resistant rocker switch by redesigning the position holding mechanism. The rocker switch of the invention comprises: a common contact point, a close circuit contact point, a movable contact point permanently coupled to the common contact point, a rocking switch connecting to the movable contact point and rocking between a close circuit position and an open circuit position, and a position holding mechanism having a spring and an extension rod coupled to one end of the spring. The extension rod is used to change the position of the force acting between the spring and the rocking button and the force acting on the spring in order to improve the life of the spring and increase heat resistance.

Abstract: This invention discloses a microswitch that is easy to assemble and manufacture. The microswitch of this invention constantly keeps the first conductive section of a resilient component for opening/closing an electrical switch in contact with the first conductive terminal in the main body of the microswitch, and houses a plate-shaped second conductive section with a contact surface inside the main body of the microswitch, so that the second conductive section of the resilient component is driven by a press button on the contact surface of the second conductive terminal to preset the signal from an initial connection state to a final connection state in order to increase the distance required for controlling the signal connection and allow the resilient component to have an effective deformation and provide the best resilience of the press button.

Abstract: A multi-direction switch that is less likely to generate erroneous movement and may reduce fabrication and assembly difficulty includes redesigned metal conductive legs of a joystick and corresponding electrode elements so that the interval between the metal conductive legs and the electrode elements increases to prevent the metal conductive legs from mistakenly connecting the electrode elements when the joystick is depressed thereby to increase oscillation amplitude of the joystick and improve the operation maneuverability thereof.

Abstract: A contact switch aims to reduce damages caused by electro-static discharge and facilitate depressing operation. It includes a casing which has a housing compartment for holding a first contact leg. The first contact leg has a first anchor flange and a second anchor flange projecting in the direction of a depressing opening. A micro mechanism is located at a lower position to increase the electro-static discharge. Due to the lower position of the micro mechanism, a retaining section may be formed by extension to space from the first anchor flange to form a depressing space so that a pushbutton may be moved therein without skewing to establish secured electric connection of the contact switch.
