Abstract
A key preloading structure including a base, a set of switches and a set of keys is provided. The set of switches is arranged on the base. The set of keys has a rotating shaft and two actuators. The rotating shaft is assembled on the base. One end of each actuator is fixedly connected to the rotating shaft, and another end is disposed on a switch of the set of switches. Each of the two actuators preloads the set of switches with a force less than a triggering force for starting the set of switches.

A key preloading structure, comprising:
- a base;
- a set of switches including two switches arranged on the base;
- and
- a set of keys having a rotating shaft and two actuators, wherein the rotating shaft is assembled on the base, one end of each actuator is fixedly connected to the rotating shaft, another end of each actuator is disposed on a switch of the set of switches each of the two actuators preloads the two switches of the set of switches with a force less than a triggering force for actuating the set of switches,
- wherein the rotating shaft has a limiting piece facing the base, and when the limiting piece and a stopping plate of the base contact each other, the two actuators preload the two switches of the set of switches with the force.
A key assembly method used in a key preloading structure comprising a base, a set of switches including two switch and a set of keys, wherein the set of keys has a rotating shaft and two actuators, and the key assembly method comprises:
- assembling the rotating shaft on the base, and restricting the rotation of the rotating shaft by a detachable component;
- temporarily connecting one end of each actuator to the rotating shaft, and disposing another end of each actuator on the set of switches, wherein each of the two actuators preloads the two switches of the set of switches with a force less than a triggering force for actuating the set of switches;
- and
- fixedly connecting one end of each actuator to the rotating shaft, and detaching the detachable component.
