DEFINITION

Classification: 315/126

(under subclass 125) Systems provided with an electrical impedance in the shunt circuit.

(1) Note. This subclass includes systems wherein an electro-responsive switch, such as an electromagnetic or thermostatic switch, is utilized to close the shunt circuit, and the switch operating means, such as the electromagnet coil, or the heater for the thermostat, is included in the shunt circuit so as to hold the switch in operated condition as long as the supply voltage is maintained.
