Abstract: The invention provides a power switch device for electronic systems equipped having a power module. The power switch device includes a first switch for activating a first signal, a second switch for activating a second signal, a logic judging module for receiving the first and second signals for logic algorithm processing, and a control module electrically connected to the electronic system and the logic judging module. The control module is adapted to generate and transmit on and off signals of the electronic system to the logic judging module. Further, the control module controls switching on the power module according to the off signal and the logic algorithm processing based on the first signal, and also controls switching off the power module according to the on signal and the logic algorithm processing based on the first and second signals.

Abstract: A circuit board fixer structure, for fixing a circuit board having at least one through hole, includes a carrier for carrying the circuit board, a pillar, and a stud. The pillar is mounted on the carrier and is formed with a first opening and a second opening corresponding to the first opening. The circuit board is fixed in place on the carrier by the pillar penetrating the through hole of the circuit board and the stud penetrating the first and second openings of the pillar to be coupled to the pillar. By the circuit board fixer structure, there is no need to use any tool to assemble and disassemble a circuit board in an electronic device, making the assembly and disassembly of the circuit board convenient to implement.

Abstract: A fastening mechanism for fastening a circuit board to an electronic device is proposed, including: a carrier used for carrying the circuit board; at least one fastening member having a first retaining portion that is connected to said carrier for coupling to at least one side of said circuit board; at least one guiding member disposed on said carrier that extends away from the direction of said fastening member; an active member disposed on said at least one guiding member that consists of a second retaining portion for coupling to an opposite side of said circuit board; and a sheathing member used for correspondingly coupling with said guiding member, thereby allowing said active member to move along said guiding member by means of the sheathing member to jointly fasten a variety of circuit boards of different sizes with said fastening member.

Abstract: A press-activated electronic component discharging facilitating apparatus is proposed, which is designed for use with a battery-powered electronic component, such as a CMOS (Complementary Metal Oxide Semiconductor) memory unit installed on a computer motherboard, for providing the CMOS memory unit with a user-operated press-activated discharging facilitating function, and which is characterized by the capability of allowing the user to facilitate the discharging of the CMOS memory unit simply by pressing the battery cell used to power the CMOS memory unit, without having to dismount the battery cell from the motherboard and flip hardware jumpers as in the case of prior art. This feature allows the discharging process of the CMOS memory to be carried out more conveniently and efficiently.
