A user-activated switch assembly comprising:
- a knob selectively moveable between a first extreme position and a second extreme position on a housing;
- said housing having a first cam surface having a first cam profile and a second cam surface having a second cam profile different from said first cam profile;
- a plunger, said housing and said knob being assembled in either a first configuration or a second configuration, said plunger contacting said first cam surface but not said second cam surface when said knob is moved from said first extreme position to said second extreme position in said first configuration and said plunger contacting said second cam surface but not said first cam surface when said knob is moved from said first extreme position to said second extreme position in said second configuration.
A user-activated switch assembly comprising:
- a knob selectively moveable between a first position and a second position;
- a housing having a first cam surface having a first cam profile and a second cam surface having a second cam profile different from said first cam profile;
- a plunger and said housing being assembled with said plunger biased between said knob and said first cam surface, said plunger moving in contact along said first cam surface while said knob is moved from said first position to said second position,
- means for mounting said plunger in either a first location in which said plunger engages said first cam surface or a second location in which said plunger engages said second cam surface, said plunger being mounted adjacent said first cam surface.
