摘要： A novel keyboard switch covering pad suitable for use in, for example, a pocketable electronic calculator is proposed which is safe from the danger of failure or erroneous operation of the LSI or other electronic devices built in the instrument when two or more of the key switches are pushed simultaneously.The keyboard switch covering pad of the invention comprises an electrically conductive rubber sheet divided into a desired number of sections and an electrically insulating sheet which serves as a common lining for the divided sections of the rubber sheet, on which the divided sections are bonded keeping an electrically insulating air gap space between each other.

摘要： There is provided a push button switch using an elastic conductive sheet having a spherical protuberance which is adapted to be deformed by a keytop for electrically connecting fixed electrodes formed on a printed circuit board. Spring means for returning the keytop is not required, so that the construction is simplified. Also, excellent switching action, operability and reliability can be ensured.
