Abstract
A switching signal input device for use with an electronic apparatus is provided. The switching signal input device includes a switch part, an operating part and a resilience element, and is capable of performing four-directional switch control actions in response to the elastic forces generated from the resilience element on two planes perpendicular to each other.
Claims4
A switching signal input device for use with an electronic apparatus, said switching signal input device comprising:
- a switch part comprising a circuit board, two forward switches disposed on a first surface of said circuit board, and two lateral switches disposed on a second surface of said circuit board;
- an operating part comprising an operating rod operated by a user to control said switching signal input device, and a touch portion coupled to said operating rod for touching one switch of said switch part upon said operating rod is operated by said user;
- and
- a resilience element for generating elasticity on first and second planes perpendicular to each other, and comprising a U-shaped portion parallel with said first plane to have said operating part clamped and supported by said resilience element such that said operating rod is operated to perform a levorotary or dextrorotary action on said first plane and a forward or backward shifting action on said second plane.
