Abstract: An electrical connector adapted for electrically connecting with a circuit board includes an insulating housing, a plurality of first and second terminals, and a shielding shell enclosing the insulating housing together with the first and second terminals. The insulating housing includes a main body, and a base body assembled to the main body. The base body defines a plurality of first and second terminal grooves. The first and second terminals are respectively assembled to the first and second terminal grooves. Each first terminal has an inclined first connecting arm connected between a first fastening arm and a first soldering arm of the first terminal, and each second terminal has an inclined second connecting arm connected between the second fastening arm and the second soldering arm of the second terminal to effectively shorten straight lengths of the first terminal and the second terminal which are stretched straight.

Abstract: A display apparatus is provided. The display apparatus includes a first video signal input terminal, a second video signal input terminal, a multiplexer, an identification detector, and a controller. The multiplexer has an identification output terminal, a first identification input terminal, and a second identification input terminal. The first identification input terminal is used for receiving a first identification code corresponding to the first video signal input terminal; the second identification input terminal is used for receiving a second identification code corresponding to the second video signal input terminal. When the identification detector detects either the first identification code or the second identification code is outputted from the identification output terminal, the controller forbids the multiplexer from being switched between the identification input terminals.

Abstract: A reciprocal switch includes a shell with a stopper located therein, a connecting unit located on two sides of the stopper for generating circuit signals, two conducting units having movable contacts located on two sides of the stopper and engaged with an elastic element, and a displacement unit located between the two conducting units and exposed outside the shell. The displacement unit may be moved when subject to an external force to move the conducting units moving to either side to press the connecting unit on one side to generate circuit signals.

Abstract: An improved press switch for channeling signal transmission or output includes a body, two terminal element mounted on the body, a first elastic element located in the body, a press element disposed in the body above the first elastic element, and a face panel for covering the body at the front side thereof. When the press element subjects to an external pressing force, a second elastic element will be driven to press the first elastic element which in turn makes contact with the two terminals for establishing an electrical link to output electric characteristics desired. When the external pressing force is released from the press element, the innate elastic force of the first and second elastic element will push the press element to its original position.
