It is for electricity! Perhaps you mean for signal, not for power?
CMOS analog switches and transmission gates should work DC --> video rates (but
the bandwidth may trail off a bit, check what the datasheet says).
Above that for RF signals then you'll find PIN diodes are used, there may be chips
with several PIN diode switches built in (I don't know, never looked for this).
CMOS switches are probably fine for you, but be aware the signal voltage must be strictly
within the power supply range, so for audio you will have to level shift or use +/- supplies.
