In addition to the magnetic interrupter shown in Fig. 59there are several types of interrupters for induction coils, but since they are seldomused in modern wireless systems, they will not be described. The electrolytic interrupter is frequently employedbut not extensively. A diagram ofconnections and a sketch is shownin Fig. 59. A lead plate of convenient size isimmersed in a dilute solution of sul-phuric acid together with a platinumelectrode covered with a porcelainsleeve. The amount of platinum ex--posed to the action of the acid is closelyregulated according to the conditionsof the circuit. When the interruptor isconnected in series with the primary winding of the induction coil the action is as follows:The current flowing through the solution from platinum point to the lead plate sets up anelectrochemical action which form a gas bubble on the tip of the platinum electrode. Thisgas bubble insulates the platinum
