ABSTRACT:
The rotary SIP switch (10) provides a single in-line package (SIP) having switching capabilities previously found in dual in-line packages (DIP) while providing more switch contacts in the same package area. The miniature rotary SIP switch (10) has a pair of oppositely disposed terminal and contact leafs (30) fixedly mounted in the base wall (27) of the switch housing (12), with the contact leaf portions (36) cantilevered within the interior of the switch housing (12). Lateral tabs (38) integral with the leaf contacts (36) effect equal spring loading upon a contact pin (44) disposed within an aperture (42) extending through a cylindrically shaped rotary driver (40). The contact pin (44) is free floating in the aperture (42) and self-centers when the rotary driver (40) is rotated and the ends of the contact pin (44) engage respective contact leafs (36). The rotary driver (40) has integral detent protrusions (48) for positioning the driver (40) and contact pin (44) in an open circuit position.
