Abstract
Improvements in pushbutton switches, characterized in that a spring contact plate is provided, comprising a switch position having a domed portion in the form of a dome and a flat sheet part surrounding the dome part, the dome-shaped part comprising, a central part and radial souls, which connect the central part to the flat laminar part, the dome part being pre-tensioned to a stable position above a plane coincident with the part bent upwards at its junction with the flat laminar part a plurality of spring contacts, which extend radially from the central part, each contact extending between a pair of radial webs, and a central contact in the central part a circuit element located below and separate from the contact plate or spring and it comprises contact areas below the spring contacts and the central contact and a push button located above the central part l to apply a downward force on the dome part relative to the flat sheet part; so the pressure exerted on the pulsator presses the central part from the stable position and makes the radial webs flex in the bent parts, jumping the central part through the plane coinciding with the flat sheet part, the spring contacts in contact with each other the contact areas and the central contact in contact with the corresponding contact area after contacting the spring contacts, the dome-shaped part returning to the stable position upon release of the push-button.
