Varistor type multi-directional input device

A varistor type multi-directional input device, comprising a base,

• an upper cover, wherein an opening is provided on an upper surface of the upper cover, and the upper cover is disposed on the base to form a central cavity;
• a rocker assembly, wherein the rocker assembly is mounted in the central cavity, comprising a rocking bar, an upper rocker arm, and a lower rocker arm;
• the upper rocker arm and the lower rocker arm are arranged in an upper and lower cross;
• the upper rocker arm is in a shape of an arch, the upper rocker arm comprises a first convex portion formed by a central upward convex, a first shaft end and a second shaft end disposed at two sides of the first convex portion, and a first through hole at a center of the first convex portion;
• the lower rocker arm comprises a second convex portion formed by a central upward convex, a third shaft end and a fourth shaft end disposed at two sides of the second convex portion, and a second through hole at a center of the second convex portion;
• the upper rocker arm and the lower rocker arm are respectively provided with an eccentric wheel;
• the rocking bar comprises an upper end, and a lower end, the lower end is riveted with the lower rocker arm, protrudes from the second through hole of the lower rocker arm and passes through the first through hole of the upper rocker arm, extends to pass through the opening of the upper cover, and the eccentric wheels of the upper rocker arm and the lower rocker arm are driven by the rocking bar to swing;
• a reset assembly, wherein the reset assembly is mounted under the rocker assembly for resetting the rocker assembly after the rocker assembly is pressed;
• an electrical component, wherein the electrical component controls a change in resistance, and is configured for converting a motion signal of the rocker assembly into an electrical signal;
• the electrical component comprises a varistor, an on-off switch;
• the on-off switch comprises a switch guide core and a conductive elastic piece;
• and
• a terminal assembly configured to output the electrical signal, comprising a varistor terminal and a switch terminal, wherein the varistor terminal is mounted on an outside of the varistor, and the switch terminal is mounted on an outside of the switch guide core;
• the switch guide core is pressed by the eccentric wheels of the upper rocker arm or the lower rocker arm when the rocking bar is pressed, to connect and disconnect the conductive elastic piece and the switch terminal.
