Abstract
An electrical switch assembly is provided comprising a housing; an actuator supported by the housing, the actuator having one or more downward extensions each having at least one rounded tip; an electrical circuit contained in the housing; an elastomeric pad comprising one or more collapsible domes overlying the electrical circuit; and one or more plunger elements supported in the housing between the at least one rounded tip and respective ones of the domes, the plunger element comprising a sloped surface to engage the rounded tip during movement of the actuator to cause the plunger element to collapse an underlying one of the domes.
Claims16
An electrical switch assembly comprising:
- a housing;
- an actuator supported by said housing, said actuator having one or more downward extensions each having at least one arcuate tip;
- an electrical circuit contained in said housing;
- an elastomeric pad comprising one or more collapsible domes overlying said electrical circuit;
- and
- one or more plunger elements supported in said housing between said actuator and respective ones of said domes, each plunger element comprising a sloped surface to engage said arcuate tip during movement of said actuator to cause said plunger element to collapse an underlying dome.
A plunger element for actuating an underlying collapsible dome in an electrical switch assembly, said plunger element comprising:
- a base portion for engaging said collapsible dome;
- and
- a body extending from said base portion, said body comprising an upwardly facing sloped surface to interact with an actuator having a portion moving in an arc towards said sloped surface and thereby effect downward movement of said plunger towards said dome.
An electrical switch assembly comprising an actuator operating on a plunger element moveable within the assembly to actuate an electrical circuit, said plunger element comprising a sloped surface for interacting with an member configured to move in an arc under control of the actuator to actuate the electrical circuit.
