Deglitched current-mode switch using JFET can be placed directly on printefficircuit board instead of front panel, to minimize hum pickup and crosstalk.JFET allows transition time of drive to be adjusted with series resistor R and shunt capacitor C to provide noiseless switching of AF signals.Diode type is not critical. Any number of switches can be ganged.- Audio Handbook, National Semiconductor, Santa Clara, CA, 1977, p2-62.
