ABSTRACT:
A miniature DIP switch (10) has actuator levers (82) projecting from a side of the housing (12). A plurality of cantilevered moveable contact arms (72) are supported by a section (34) of the base (30), and a plurality of oppositely disposed cantilevered contact arms (62) are supported by a complementary section (32) of the base. A plurality of insulative rotatable lever actuators (80) are supported each by a respective moveable contact arm (72). Each actuator (80) comprises a lever (82) projecting from a respective opening (18) In the housing (12), an arcuate bearing surface (86) engaging an arcuately shaped boss (22) in the housing, a pair of depending side walls (88) each having arcuately shaped ends (90), and a cam protrusion (87) disposed between the depending side walls (88) and engaging its respective moveable contact arm (72). Rotation of the actuator (80) about the arcuately shaped boss (22) causes slideable engagement of the cam protrusion (87) with the moveable contact arm (72) whereby the moveable contact arm (72) is biased into engagement with its respective contact arm (62). A detent notch (77) in each moveable contact arm (72) provides a positive detent "feel" and "snap" upon engagement of the cam protrusion (87) with the notch (77).
