ABSTRACT:
An input device adopts a low cost and simple terminal design to replace the conventional grating and instruction switch structures that are costly and complicated. The input device includes a braced rotary member turnable, tiltable leftwards and rightwards, and movable upwards and downwards for selected displacements and an instruction mechanism located within the displacements to receive forces and be driven by the rotary member to generate instructions. The instruction mechanism has abutting mechanical terminals to contact with each other to generate instruction signal output.
