Title: Keyboard switch
Inventor: BURAIAN JII SUPURETSUDOBARII
IPC: H01H13/702
Filed: 1988-12-19
Abstract: PURPOSE: To establish a good connection by a method in which a dome displaces a circuit board to a recess and provides electrical connection of an open contact when the dome having conductivity on its inside is pressed toward a base member. CONSTITUTION: When a dome is crushed by finger pressure, a conductive layer on the back side of the dome makes contact with fingers 17 and 17A, being alternately intricate on a printed circuit, at a switch position. Moreover, the finger pressure shifts the printed circuit located at the switch position so as to be warped toward a recess 14 of a base member 12. When key buttons are arranged on the respective domes, the above working is repeated. In this manner, the conductive layer 22 is brought into close contact with the fingers 17 and 17A. This can assure a good contact between the layer 22 and the fingers so that a reliable keyboard switch can be obtained.
