A foot-control switch with a security mechanism includes a base body, a printed circuit board, a pedal, and a latch. The printed circuit board is set in the base body and the pedal is installed on the base body. The latch installs near by the pedal. The pedal is electrically connected to the printed circuit board via the latch. An electrical conduction between the printed circuit board and the pedal is enabled when the latch and the pedal are pressed. Therefore, the printed circuit board and the pedal are connected when the pedal is unlocked through the latch, and then the follow-up driving signal is outputted. In this way, the mistaken accident of touching the foot-control switch is avoided in order to improve the usage safety of the foot-control switch.本發明係關於一種具有安全機制的腳控開關，此腳控開關，包括一座體、一電路板、一踏板器以及一鎖定器，電路板容置在座體；踏板器裝設在座體；鎖定器鄰近於踏板器配置，踏板器透過鎖定器和電路板電性連接；其中，鎖定器及踏板器被按壓時，將令電路板和踏板器電性導通。藉此，踏板器必須透過鎖定器作解鎖動作，電路板和踏板器才會相互導通，以進行後續驅動訊號之輸出，進而避免發生誤觸腳控開關，以提高本發明腳控開關之使用安全性。
