The invention relates to an isolated type electronic switch circuit. The isolated type electronic switch circuit comprises a first sub-circuit and a second sub-circuit, wherein each sub-circuit separately comprises a power isolation circuit, a signal isolation circuit, a control circuit and a switch circuit, and the switch circuit comprises a controlled switch; for each sub-circuit, a power signal is separately input to the switch circuit and the control circuit after being processed by the power isolation circuit; a control signal is input to the control circuit after being processed by the signal isolation circuit, and a signal output by the control circuit controls the opening and closing of the controlled switch included by the switch circuit; and one contact of the controlled switch of the first sub-circuit is connected with one contact of the controlled switch of the second sub-circuit, and the other contact of the controlled switch of the first sub-circuit and the other contact of the controlled switch of the second sub-circuit are taken as two output ends of the isolated type electronic switch circuit. The isolated type electronic switch circuit disclosed by the invention is long in service life, does not have mechanical noises, and is fast in response.
