Abstract : A study was made of the problems associated with setting up noncontact switching circuits made up of semiconductor elements. It is shown that the same switching circuit may be used for measuring low potentials and for switching strong signals. P16 type germanium low-power transistors should be used for setting up weak signal switching circuits. The advantages of these transistors are that they have low resistance in the open position and low residual voltage. P202 and P4 high-power transistors should be used for switching strong signals. In switching, transistors may be used successfully and find a wider application for the signal switching level above one volt. Silicon switching transistors show promise for this use. The design of transistorized switching circuits could be made easier if industry produced transistors with standardized values of the switching characteristics.
