The limiting component includes a side plate, a thrust part, a stop part, a slide and a pit. By pressing down the touch plate, a metal conductive protrusion is provided on the bottom surface of the touch plate, and a retaining spring is provided on the top surface of the base to clamp the protrusion to achieve electrical connection. When the touch plate is flipped to disengage the protrusion from the retaining spring, the touch plate drives the thrust part and the stop part to slide in the slide, and the contact on the wall of the stop part enters the pit to lock the position of the thrust part and the stop part, so that the touch plate has a certain resistance after flipping, preventing the protrusion of the touch plate from contacting the retaining spring to cause circuit connection.
