The present invention provides an elevator button kit for adding contactless sensing to control operations of an elevator though an elevator controller. The elevator button kit comprises a plurality of buttons and a bus. Each button comprises a primary switch for directly controlling the elevator controller, wherein the primary switch requires physical contact to the button to trigger the same; a secondary switch adapted to be triggered electronically; a position sensor for sensing presence of objects within a sensing range; and a microcontroller (MCU) having both the position sensor and the secondary switch connected thereto. The bus connecting the MCUs of the plurality of the buttons to form a MCU network, wherein operationally, range data from each position sensor is acquired by the connected MCU and broadcasted to the other MCUs through the MCU network, and each MCU processes the collected range data from the MCU network to determine whether to send a trigger signal to activate the connected secondary switch to control the elevator controller. A method thereof is also provided.
