Abstract
A rotary motion switching apparatus is usable with a circuit interrupter that is situated in a NEMA box or other box and employs an attachment system. An access port that is formed in a wall of the NEMA box or other box permits a shaft having a handle at an end thereof to be connected with the rotary motion switching apparatus. The rotary motion switching apparatus includes a universal joint on a rotational component that enables operation of the handle and shaft without binding on the wall of the NEMA or other box even if the access port in the box is offset from an axis of rotation of the rotational component.
