Title:
PASSIVE REBOUND SWITCH HAVING VARIABLE NUMBER OF BUTTONS
Document Type and Number:
WIPO Patent Application WO/2018/177365
Kind Code:
A1
Abstract:
A passive rebound switch having a variable number of buttons, the passive rebound switch comprising at least one button configuration cover, at least one energy collecting support, at least one detection switch, at least one housing, at least one power generation device, and at least one signal transmission circuit. The button configuration cover comprises at least one button, and each button is detachably and pivotally connected to the housing. The power generation device, the signal transmission circuit, and the detection switch are accommodated in an accommodation cavity defined by the button configuration cover and the housing. Every rebound movement of the button resists a rebound movement of the energy collecting support, so as to trigger the power generation device to convert, at least once, mechanical energy into electrical energy to power the signal transmission circuit. The energy collecting support is disposed between each button and the power generation device. The detection switch pre-turns on an I/O interface of an encoding device of the signal transmission circuit prior to the power generation device generating power. When powered, the signal transmission circuit transmits at least one control signal.
