(under subclass 11) Subject matter provided with an electrical impedance in the shunt circuit.
(1) Note. This subclass includes arrangements wherein an electroresponsive switch, such as an electromagnetic or thermostatic switch, is included in the shunt circuit, and the switch actuating means, such as the 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.
