Light touch button switch structure: switch panel and convex button connected with switch panel are characterized in that the button is connected with the panel through arc connecting strips on both sides of the button. The button, connecting strip and panel are preferred by injection moulding, and the button has a decorative set on the jacket. The arc connecting strip of the utility model has certain elasticity because of its own thin strip shape, so when the central button is pressed and released, the elastic effect of the arc connecting strip will make it reset, so there is no need to set a reset spring under the button, and at the same time, the structure of touching the button switch can be simply realized by an integral injection molding, thus greatly facilitating the manufacture and assembly. 。 The working principle of proximity switch is classified as follows: the working principle of proximity switch: the working principle of inductance proximity switch. The inductance proximity switch belongs to a position sensor with switching output. It consists of LC high frequency oscillator and amplification processing circuit. When approaching the oscillating inductor which can generate electromagnetic field, the metal object generates eddy current inside the object. This eddy current reacts on the proximity switch, attenuates the oscillation ability of the proximity switch, and changes the parameters of the internal circuit, thus identifying whether there is a metal object approaching, and then controlling the switch on or off. The object that this proximity switch can detect must be a metal object.
