Abstract
The invention provides a switch contact device with two rotary tables, which comprises a main rotary table arranged on a rotating shaft, wherein, the main rotary table is provided with a connecting shaft, and by driving the connecting shaft, the main rotary table is driven to rotate around the rotating shaft; an auxiliary rotary table which is arranged on the rotating shaft and concentrical with the main rotary table, wherein, the auxiliary rotary table is provided with a stop block and a switch contact; a place on the main rotary table, which corresponds to the stop block of the auxiliary rotary table, is also provided with a stop block. When the main rotary table is driven to rotate around the rotating shaft, the stop block of the main rotary table presses against the stop block of the auxiliary rotary table to drive the auxiliary rotary table to rotate around the rotating shaft, thus driving the switch contact to rotate so as to open or close the switch contact. Under the condition that the state of the main rotary table is not changed, the auxiliary rotary table can be driven independently to rotate in virtue of an external force, therefore, the switch contact can be driven to rotate so as to open or close the switch contact, without changing the state of the main rotary table.
