  • Structure for contact points of a shift switch used in a computer
    Patent number: 5587886
    Abstract: A structure for contact points of a shift switch used in a computer. The structure includes an elastic contact plate disposed under the shift switch and having projecting contact points to contact the corresponding conductive contact portions of the circuit board. A sloped slot is formed between adjacent contact portions to separate the contact portions from each other and to avoid detachment and scattering of the conductive material of the contact portions. The contact points are designed with an elongated shape so as to provide a smooth sliding motion of the contact points through the sloped slots.
