Movable contact assembly for a switch

A movable contact assembly of a switch for use with a stationary contact assembly including stationary contact elements comprising:

• movable contact elements engageable with the stationary contact elements;
• a movable contact arm carrying said movable contact elements;
• an electrically insulating contact holder movable between open and closed positions, said contact holder holding said movable contact arm;
• a compression spring for resiliently holding said movable contact arm relative to said contact holder;
• a spring retainer disposed between said compression spring and said movable contact arm;
• means for guiding said movable contact arm into a predetermined operative positional relationship relative to said movable contact holder under the spring force of said compression spring including means on said spring retainer defining a laterally spaced pair of first and second oppositely facing sloped guiding surfaces;
• means on said movable contact arm defining a pair of first and second sloped guided surfaces facing said pair of first and second guiding surfaces of said spring retainer;
• said sloped guiding surfaces of said spring retainer, in cooperation with the sloped guiding surfaces of said movable contact arm, guiding said movable contact arm into a predetermined operative positional relationship relative to said movable contact holder due to the spring force of said compression spring.
