The invention relates to a two-position spring actuating mechanism for switchgear, which comprises a casing. The casing comprises a bottom plate, a rotating shaft is rotatably assembled on the bottom plate, a spring support is assembled on the rotating shaft in a rotation stop manner, a driving mechanism is arranged between the spring support and the casing and comprises more than two guide arms and driving springs sleeved on the guide arms, vertical shafts are rotatably assembled at two ends of each guide arm respectively, at least one of the two vertical shafts of each guide arm is axially and movably matched with the corresponding guide arm, one of the two vertical shafts of each guide arm is vertically arranged on the spring support while the other of the two vertical shafts of each guide arm is arranged on the casing, a point on the axis of one of the two vertical shafts of each guide arm positioned on the casing and the axis of the rotating shaft determines an interface, the other vertical shaft rotates along with the rotating shaft and is provided with a first station and a second station which are arranged on two sides of the interface respectively, and the vertical shafts positioned on the spring support are the same in the rotation direction around the rotating shaft when moving from the first station to the second station. The two-position spring actuating mechanism for the switchgear solves the problem that an existing spring actuating mechanism for switchgear is large in size.
