  • X-Y input device
    Patent number: 4739315
    Abstract: An X-Y input device comprises a position sensor, a switch for use in signal processing of the position sensor, and a switch lever actuatable by pressing by the finger the outwardly-projecting key portion to operate the switch to become closed and opened, and a case consisting of a bottom plate and a cap mounted thereon and adapted to hold the switch and switch lever. The input device further comprises posts on the bottom plate, each post supporting the associated switch lever at an intermediate site between the key portion at one end of the switch lever and the abutment portion for abutting against the undersurface of the top wall of the cap at the other end, so that the switch lever can be resiliently flexed by pressing the key portion. These features of the invention enables reaction of the key portion to finger's pressure to remain constant and makes installation of the switch lever simpler.
