The present invention relates to a footboard type button of an elevator. The purpose of the present invention is to provide a footboard type button of an elevator capable of allowing a passenger to call an elevator car without a separate operation of a button and automatically keep a door open when a passenger gets into and out of an elevator by installing a footboard type button using a piezoelectric element on the bottom surface of a platform on each floor of a building in which an elevator is installed. According to the present invention, the footboard type button of an elevator is installed as a call input button on the bottom surface on each floor of a platform of a building in which an elevator car is operated. The footboard type button has multiple piezoelectric elements mutually connected in series while in an arranged state. Multiple LEDs are arranged while connected with the piezoelectric elements in series. A sensing unit is place on the last LED connected with the piezoelectric element in series, to generate a relevant signal by detecting the operation of the piezoelectric element. |
