Operating mechanism for isolation grounding switch and isolation grounding switch

The utility model provides an operating mechanism for an isolation grounding switch and the isolation grounding switch. The operating mechanism comprises a driving module; the transmission module comprises a first mechanical transmission chain, a second mechanical transmission chain and a third mechanical transmission chain, the first mechanical transmission chain and the third mechanical transmission chain share a transmission main shaft, and the second mechanical transmission chain and the third mechanical transmission chain are arranged in parallel; the auxiliary switch module comprises an auxiliary switch and a trigger part; and the signal module comprises a signal unit and a triggering component. The driving module drives the isolation grounding switch to move between a switching-off position and a switching-on position through the first mechanical transmission chain, and drives the triggering part to trigger the auxiliary switch to generate a first indication signal indicating the switching-off position
