Abstract
A multiple positioning assembly with integral switch contact includes a cylindrical housing along with a ball assembly including a ball portion received by the cylindrical assembly. The ball portion includes an electrically conductive surface and a neck extending therefrom. A plurality of spaced apart spring retainers are disposed within the cylindrical housing with electrically conductive coil spring contacts therein. Adjacent spring contacts complete an electrical circuit through the ball portion surface when in simultaneous contact therewith. Spring contacts further enable positioning of the ball portion within the cylindrical housing for conical movement of the neck with the ball portion being axially moveable between the spring contacts.
Claims24
A multiple positioning assembly with integral switch contacts, the assembly comprising:
- a cylindrical housing;
- a ball assembly including a ball portion received by said cylindrical housing, said ball portion having an electrically conductive surface and including a neck extending therefrom with a bore through said neck and ball portion;
- a plurality of spaced apart spring retainers disposed within said cylindrical housing, each spring retainer having a groove open toward said ball portion;
- an electrically conductive coil spring contact disposed in each retainer groove;
- adjacent spring contacts completing an electrical circuit through the ball portion surface when in simultaneous contact therewith and enabling positioning said ball portion within said cylindrical housing for conical movement of said neck, said ball portion being axially moveable between spring contacts;
- and
- one of the spring contacts most proximate to an end of said cylindrical housing preventing withdrawal of said ball portion from said cylindrical housing.
