The semi-conductor analog switch circuit

By replacing the connector switch with the analog electric switch, the spark and RF noise can be avoided. In the figure is the knot FET transistor, op-amp circuit and other equivalent mechanical circuit. When there is the control signal (the LEV is higher than 10V) of the input signal UE (or UE1, UE2 and so on) on B terminal, the op-amp generates the output signal UA(inverting phase). In Figure 2 is the circuit of the same type.
