Abstract
A current source switch circuit has at least one transistor forming part of a current source, and one switch for controlling the supply of an electric current from the transistor to a load. A voltage application unit applies a voltage having a value in an operation state as a current source to a transistor forming part of the current source while no electric current is provided from the switch to the load.
