Abstract: The present invention discloses an electronic device charger, mainly comprising: a voltage converting module, a microprocessor, a low voltage detecting unit, and an over voltage sensing unit. When a rated output voltage of a vehicle battery of an electric vehicle is detected to be lower than a first threshold voltage by the low voltage detecting unit or found to be higher than a second threshold voltage by the over voltage sensing unit, the microprocessor immediately stops the vehicle battery providing electrical power to at least one portable electronic device owned by the driver of the electric vehicle. Therefore, the electronic device charger can not only save the energy of the vehicle battery while the vehicle battery is at a low voltage state, but also protect the portable electronic devices from being damaged by the electrical power as the rated output voltage of the vehicle battery exceed a normal voltage level.

Abstract: Disclosures of the present invention describe an industrial socket, comprising: an insulation body, a plurality of electrical connectors, a plurality of actuating units, and a plurality of elastic elements, wherein each of the actuating units comprises a slant surface portion and a cover portion. It is worth explaining that, when an electrical plug is inserted into a receiving opening of the insulation body, the slant surface portion enters a notch by a pushing force applied by the electrical plug, such that the cover portion correspondingly moves with the motion of the slant surface portion, so as to stop the shielding to an electrical end of the electrical connector. Therefore, this novel industrial socket has many outstanding functions of fool-proof, dustproof and contact protection.

Abstract: The present invention discloses a dual-actuator switch, comprising: a base, a first electrical connection member, a second electrical connection member, a first isolation sleeve cylinder, a second isolation sleeve cylinder, a first actuator, a second actuator, and a cover.

It is worth noting that, the electrical connection members are isolated from the actuators by the isolation sleeve cylinders during the whole electrical switching procedures. As a result, ambient moisture is absolutely blocked from getting into the base for infiltrating the electrical connection members during the up and/or down motion of the actuators.
