Abstract

A switch apparatus is provided. The switch apparatus includes a signal control switch, a switch circuit, a blocking capacitor and a surge current dissipation circuit. The signal control switch and the switch circuit are respectively controlled by a first control signal and a second control signal to be turned on or off. The blocking capacitor is serially coupled between the switch circuit and a reference voltage end. The surge current dissipation circuit includes a Zener diode circuit or at least one diode circuit, and the at least one diode circuit has one or more diodes coupled in series. The one or more diodes coupled in series are coupled between two ends of the surge current dissipation circuit according to a first polarity direction.
