1. An electrical switch, comprising:
a first terminal, a second terminal, and a third terminal;
a solid-state alternating current (AC) switch connected in an electrical path between the first terminal and the second terminal; and
a microcontroller configured to control operation of the solid-state AC switch to control power flow between the first terminal and the second terminal;
wherein the microcontroller is configured to communicate with a second electrical switch over a data line that is connected to the third terminal of the electrical switch and to the second electrical switch, to implement multi-way switch control for controlling power to a load; and
wherein the microcontroller is configured, upon power up, to perform a master/slave self-identification process to determine whether to operate the electrical switch in a master mode or a slave mode, based on sensing a voltage level on the data line that is connected to the third terminal of the electrical switch.
