Abstract
The invention provides an electric appliance button. An accommodating cavity is formed in an accommodating groove; the accommodating groove is provided with an elastic fixed part and a rigid pressing part; the elastic fixed part is provided with an upper annular cover and a lower annular cover to form a first clamping groove; the peripheries of the upper annular cover and the lower annular cover are connected by a cap wall, and the lower end of the cap wall is clamped in a connecting groove in the side wall of the accommodating groove; an upper fixed edge and a lower fixed edge are arranged on the periphery at the lower end of the cap wall to form a second clamping groove; the rigid pressing part is provided with a first clamping plate clamped in the first clamping groove; the first clamping plate is provided with a pressing plate; a guiding column is arranged below the first clamping plate, and movable contacts are arranged on the lower end head of the guiding column; a first static contact and a second static contact are arranged on the bottom surface of the accommodating cavity; the exterior of the guiding column is sleeved with an elastic part; an upper fixed end is arranged at the upper end of the elastic part while a lower fixed end is arranged at the lower end; and the upper fixed end is clamped in an upper fixed groove in the first clamping plate while the lower fixed end is clamped in a lower fixed groove in the accommodating cavity. Dual reset is realized by virtue of the cap wall and the elastic part, so that getting stuck of the button can be avoided; and in addition, the electric appliance button is high in sealing property, and access of dust and water can be avoided.
