Abstract: When the plunger is depressed, the actuating blade acts on the cam to rotate the cam detent and wiper assembly 60*. The rotating detent cooperates with the fixed detent to give the ''''feel'''' and indexing action. The fixed contacts are arranged so one of the three wipers will always contact a ''''hot'''' contact while one of the wipers will contact either the low beam or high beam contacts in the static (detented) position. During the switching action, which occurs after the detent action starts and, therefore, at high speed, there is always an interval when both the high and low beam contacts are engaged by the wipers to make the new circuit before breaking the old circuit. The ''''hot'''' circuit is never broken and arcing is minimized. The use of three blades instead of two increases switch life. And safety is improved since there is no time during which no headlamp circuit is made.
