Abstract: A keyboard switch for a keyboard includes a base secured to a plunger that reciprocates with respect to the base and is biased away from the base. An electrical contact assembly is positioned within a cavity defined by the base and the plunger. The electrical contact assembly remains in an electrically open state when the plunger is furthest from the base, but the electrical contact assembly enters an electrically closed state when the plunger is longitudinally moved downwardly by force towards the base. In this regard, a cam protruding from a side portion of a body of the plunger has a profile surface that contacts the electrical contact assembly as the plunger is longitudinally moved towards the base. A curved profile of the cam that incorporates a concave arc uniquely changes the amount of force experienced by the typist at different points of the downward motion of the plunger.
