SWITCH

摘要

A switch includes a fixed contact 3 fixed in a container in which an insulating gas is filled and a movable contact 4 provided to be reciprocatingly movable with respect to the fixed contact and configured to come into contact with and separate from the fixed contact. The switch further comprises a pin 11 provided in the container and configured to move along an arcuate track. A groove 12 in which the pin is fit and is movable is formed in the movable contact. The groove includes a linear groove 12a linearly extending substantially perpendicularly to a moving direction of the movable contact and substantially in parallel to a plane including the moving track of the pin and an arcuate groove 12b that communicates with the linear groove and overlaps the moving track of the pin. The pin moves in the linear groove, whereby the movable contact reciprocatingly moves.
