A video graphics array (VGA) interface switch apparatus includes first to third VGA interfaces, a single-pole double-throw (SPDT) switch, a switch control chip, and first to sixth electronic switches. The first VGA interface is connected to the second and third VGA interfaces through the switch control chip and the electronic switches. The SPDT switch is used to control the first VGA interface to be selectively connected to the second or third VGA interface.

Video graphics array interface switch apparatus

A switch apparatus includes first to third video graphics array (VGA) interfaces, first to sixth universal serial bus (USB) interfaces, a single-pole double-throw (SPDT) switch, and first to eighteenth electronic switches. The first VGA interface is connected to the second and third VGA interfaces through the electronic switches. The first USB interface is connected the second and third USB interfaces through the electronic switches. The fourth USB interface is connected to the fifth and sixth USB interfaces through the electronic switches. The SPDT switch is used to control the first VGA interface to be selectively connected to the second or third VGA interface, and control the first USB interface to be selectively connected to the second or third USB interface, and control the fourth USB interface to be selectively connected to the fifth or sixth USB interface.

Switch apparatus for switching display, keyboard, and mouse

A programmable logic device (PLD) data transfer cable includes a parallel interface, a programming interface, and a logic control circuit. The parallel interface is used for connecting to PLDs. The logic control circuit includes a first group of transmission channels, a second group of transmission channels, a first group of switches, and a second group of switches. The first and second group of switches control the working status of the first and second group of transmission channels respectively. The electrical connections between pins of the parallel interface and the programming interface when first group of transmission channels are activated are different with those when second group of transmission channels are activated.
