Abstract
A switch assembly including a switch and a high impedance element used for energy harvesting purposes that are connected to a power line and assembly electronics. The high impedance element has higher impedance than the switch so that current flows through the switch from the power line when the switch is closed and through the high impedance element from the power line when the switch is open. The switch assembly also includes a current sensing device, such as a current sensing resistor, electrically coupled in series with the high impedance element and the electronics. By measuring the current flow using the current sensing device, it is possible to infer the voltage across the high impedance element since its impedance is known. This voltage can be used to provide point on wave closing of the switch and to determine the line voltage magnitude.
