A and B can be any signal and c is the on/off command signal.So this circuit should be conduct any signal with maximum 1A current. regards,[/img]

For small signal applications, look for 4066, 4053, 4052, and other CMOS switches. It can be discrete too, with diodes, or MOS.

DC capable relays are generally using anti-serial MOSFETs and e.g. a photovoltaic gate driver, if isolation is required.
