Input switch for reversing the sense of an amplifier in a single loop heating-cooking system
摘要:
A single-pole, double-throw switch and a pair of input resistors connected in series between the alternative terminals of said switch may be employed between a pair of condition sensitive terminals and a pair of input terminals for an amplifier to reverse the sense of the amplifier output.
