Abstract
A power switch configured for use in a multi-way switch system is provided. The power switch includes one or more switching elements configured to selectively couple a load to a power source. The power switch includes a power metering circuit and a communications circuit. The communications circuit can be configured to provide communications between the power switch and at least one other power switch in the switch system. The power switch can include a control device configured obtain data from the power metering circuit. The data can be indicative of power consumption of the load. The control device can be further configured to determine whether the power switch is a master power switch in the multi-way switch system based on the data.
