The novel elevator button comprises an upper cover and a base, a cavity is formed in the base, a circuit board and a supporting piece are arranged in the cavity, a placement groove is formed in the supporting piece, a function indication key is arranged in the placement groove, the function indication key comprises an installation part and a pressing part, and the installation part and the pressing part are arranged on the base. The pressing part extends out of the upper cover and is used for being pressed by an operator, the mounting part is used for fixing the function indication key on the supporting piece, contact switches are arranged on the circuit board, and when the function indication key is pressed, different contact switch combinations are triggered through the supporting piece and fed back to the circuit board to achieve the function of the function indication key. According to the invention, through the contact switch, the support member and the function indication button, when one button is pressed, conduction of any button position can be realized through the effect of the support member, so that the contact reliability is effectively improved, and the problem caused by the fact that a correct position cannot be pressed in the prior art is avoided.
本发明为一种新型电梯按钮,包括上盖以及底座,所述底座内形成有腔体,所述腔体内设置有线路板、支撑件,所述支撑件上形成有安置槽,所述安置槽内设置有功能指示按键,所述功能指示按键包括安装部以及按压部,所述按压部伸出所述上盖用于操作人员按压,所述安装部用于固定功能指示按键在支撑件上,所述线路板上设置有接触开关,按压所述功能指示按键时通过支撑件触发不同接触开关组合并反馈至线路板实现功能指示按键的功能。本发明中通过接触开关、支撑件以及功能指示按健来实现,当按下其中一个按键时,通过支撑件的作用能够实现任意按键位置的导通,有效的提高了接触的可靠性,避免了现有技术中按压不到正确位置所带来的问题。
