Electrical switch single sliding/rotary actuator

A switch assembly comprising:

• a housing that includes upper and lower housing parts with peripheries that are joined, said housing parts forming an internal cavity between them, said cavity having top and bottom walls that have aligned bores;
• an actuation member having an upper portion projecting through the bore in said upper wall and having a lower portion lying in said bore in said lower wall, said actuation member being vertically slideable in said bores;
• a resilient dome-shaped switching element;
• pair of contacts including a first contact in engagement with a periphery of said switching element and a second contact lying under a center portion of said switching element;
• said dome-shaped switching element has a hole and said actuation member lower portion projects through said hole.

An electrical switch assembly, comprising:

• a housing having an upper housing portion with a vertical upper bore, said bore having a vertical axis;
• an actuation member which is moveable vertically along said vertical bore and which is pivotable about said axis;
• a resiliently deformable switching element which has a first part that is connected to a first terminal and that is supported on said housing against downward movement, said switching element having a second part that is biased to an upward position but which can be resiliently downwardly deflected against a second terminal;
• a conductive coding wheel which is rotatably fixed to said actuation member to pivot about said axis with said actuation member, said coding wheel having at least one conductive tooth and one space lying on an imaginary circle centered on said axis;
• a plurality of contacts with engaging parts positioned in vertical alignment with said circle, so each of the contacting parts engages and does not engage a selected one of said engaging parts as said coding wheel is selectively turned;
• said engaging parts positioned to allow vertical movement of said actuator member to downwardly deflect said second part of said switching element against said second terminal and to release said second part of said switching element to allow said second part and said actuation member to move to an upward position;
• said second part of said switching element has a hole, said actuation member has a lower portion that extends through said hole, and said housing has a lower housing portion with a lower bore that lies below said hole and that guides said lower portion of said actuator member in vertical movement.
