  • Patent number: 5612520
    Abstract: A suspend (sleep) switch for a portable electronic device, such as a notebook computer, is mounted on a printed circuit board. The suspend switch includes a first contact which is positioned in juxtaposed relationship with a second contact. The contacts are formed from an electrically conductive metal or other electrically conductive material which is sufficiently resilient to support an actuator and to hold the two contacts apart in normal operation. In addition, the resiliency of the two contacts allows the two contacts to adjust to different distances between the printed circuit boards on which the contacts are mounted and the cover of the electronic device which constrains the actuator. When the cover of the electronic device is closed, the actuator pushes the two contacts into electrical contact, preferably with a wiping motion, to provide an electrical connection which can be sensed by circuitry on the printed circuit board.
