A switching mechanism and an isolating switch relate to the technical field of low-voltage apparatuses. The switching mechanism comprises a handle rotating shaft and a rotating disc connected with the handle rotating shaft. A first matching part is arranged on the rotating disc and is used for being in driving connection with a lever of a connecting rod mechanism of the isolating switch; the handle rotating shaft is driven to rotate at an angle equal to or larger than 90 degrees to drive the rotating disc to rotate, and when the rotating disc rotates, the first matching part drives the lever to swing at an acute angle so that the connecting rod mechanism can be switched off or switched on. The switching mechanism is simple in structure, and can realize the switching of the operation modes of the connecting rod mechanism of the molded case circuit breaker, so that the connecting rod mechanism of the molded case circuit breaker can be applied to an isolating switch. 一种转换机构及隔离开关，涉及低压电器技术领域。该转换机构包括手柄转轴和与手柄转轴连接的转动
