Patent
CA 2364935
A switch assembly includes a housing within which is arranged a convex, over-center spring which deforms when pressure is applied to a push button. In a default position, the push button sits atop an apex of the spring, with the spring being spaced from a contact associated with a first electrical lead. One end of the spring projects from the housing and defines a second electrical lead. When pressure is applied to the push button, the spring is pushed into electrical communication with the contact, thus completing a circuit between the electrical leads. In a first embodiment, a base housing member and a separate snap-on cover is provided. In a second embodiment, the cover is attached to the base housing via a living hinge. In both the first and second embodiments, the cover assists in holding the spring in the default position.
