CONTACT MAKING AND BREAKING APPARATUS OF COMBINATION SWITCH

摘要

PURPOSE: A contact making and breaking apparatus is provided to be capable of securing a constant operation speed regardless of an outer temperature variation and to be easy to install and repair. CONSTITUTION: An operation shift(1) is disposed along to an axis direction of a rotation shaft of a moving contact part and is connected to the rotation shaft so as to be rotated and moved. A front support plate(3) and a rear support plate(5) are disposed at both ends of the operation shift(1) so as to rotate and support the operation shift(1). A moving plate(7) is coupled so as to be rotated with regard to the operation shift(1). The first and second fixing plates(9,11) are coupled to the other end of the operation shift(1) so as to be rotated with the operation shift(1). A driving motor(13) provides a driving force for rotating and moving the moving plate(7). A transmission part(15) provides a driving power of the driving motor(13), with the transmission part(15) interposed between the driving motor(13) and the moving plate(7).
