ABSTRACT:
Electronic switches are used for switching the fine-tuning variable resistors in the electronic tuners of television receivers or stereophonic systems, and consist of a number of thyristors with P- and N-gates connected in parallel. The cathodes of the thyristors are connected in commmon, while a switch is connected to the anode circuits of said thyristors. A detector having an input connected to the N-gate circuits of the thyristors and an output connected to said switching means; and a number of input terminals each connected to the P-gate of each thyristor are also provided.
