Abstract
PURPOSE: To provide a switching circuit for an electronic instrument, in which the discharge of a capacitor for charging such a voltage as corresponds to the pushing speed of key is controlled by both such a capacitor as has its charged current preset in accordance with the key pushing voltages and a transistor, thereby making it possible to produce such a tone as follows the strength of the touches upon the keys.
