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 structure includes a base plate, a key cap, a supporting member, a link member, and a buffer member. The base plate includes a body portion and a protrusion portion protruding upward from the body portion. The body portion has an accommodating hole, the accommodating hole corresponds to the protrusion portion, and the protrusion portion has an opening. The key cap is disposed above the base plate. The supporting member is disposed between the key cap and the base plate. The link member includes a main body portion and an end portion. The main body portion is pivotally connected to the key cap, and the end portion is disposed at the opening of the protrusion portion. The buffer member is located below the end portion, and the end portion leans against the buffer member.

A passive rebound switch includes an actuation button, an energy collecting module, a detection control, a housing, a power generation module, and a signal transmission circuit. The actuation button is detachably and pivotally connected to the housing. The power generation device, the signal transmission circuit, and the detection control are accommodated in an receiving chamber formed between the actuation button and the housing. When the actuation button is actuated to move in reciprocated rebounding movement, the energy collecting module is actuated to trigger the power generation module for converting mechanical energy into electrical energy to power the signal transmission circuit for transmitting a control signal. The energy collecting module is disposed between the actuation button and the power generation module. The detection switch pre-activates an I/O interface of an encoder device of the signal transmission circuit prior to the power generation module for generating the electrical power.
