Quad bilateral ic chip--keeping the on-state resistance low over the full operating-signal range by eliminating the variation of the - voltage,electronic switch
Electrical switch--special design and it is in workmanship it is the best replacement for your old, broken one,dip switch
Bilateral ic chip--the on-state resistance of the bi-directional is relatively constant over the full signal-input range,electrical switch
Logic gate chips--replace your old or broken logic gate with a new one,electrical switch
Analog switch--on-state resistance is flat over the entire peak-to-peak signal range,electrical switch
