Abstract
A movable contact assembly for an electrical switch includes a movable contact and a pair of supports, each support including a bottom face and a support body perpendicular thereto. Each support body includes: a cavity for holding the movable contact disposed symmetrically at each end of a diameter of the bottom face, an inner and outer hook pair extending along the axis of the support body and being disposed symmetrically to the two sides of the diameter; and a projecting tongue and recess pair extending along the axis of the support body and being disposed symmetrically to the two sides of the diameter. The movable contact-holding cavity can hold the movable contact, the two supports can engage with each other in the direction of the axis, and the pair of the supports and the movable contact are assembled together to form the movable contact assembly.
