Abstract
Official abstract text for this publication.
Provided is a switching apparatus that switches a connection state between two terminals, comprising a switch that switches the connection state between the two terminals according to a control voltage supplied thereto; a driving section that provides the switch with the control voltage corresponding to a control signal supplied thereto; and a changing section that changes the control voltage output from the driving section, according to a designated switching time. The changing section may change power supplied as a power supply to the driving section, according to the designated switching time. The changing section may change the control voltage output from the driving section prior to switching of the switch.
