Abstract
Official abstract text for this publication.
A switch triggering device of an electronic device is provided. By the switch triggering device, a switch on a top surface of a circuit board can be controlled from a bottom side of the electronic device. The switch triggering device includes a first linkage element, a second linkage element and a third linkage element, which are arranged between an upper cover and a base of the electronic device. The second linkage element is pivotally coupled to the upper cover. The two ends of the second linkage element are pivotally coupled to the first linkage element and the third linkage element, respectively. When the first linkage element is pressed from the base and moved toward the upper cover, the second linkage element is rotated relative to the upper cover. Consequently, the third linkage element is correspondingly moved toward the switch so as to trigger the switch.
