Tact switch

The utility model discloses a tact switch, comprising a main body which is provided with a touch push rod, and a first conductive pin and a second conductive pin extending outside. The main body is internally provided with a contact spring; one end of the contact spring is in fixed connection with the second conductive pin, and the other end is in a movable end; the contact spring is continuously provided with an inclined plane and a step plane; a touch head of the touch push rod is provided with a positioning plane corresponding and cooperating with the step plane; a reset spring is arranged between the contact head and the main body. According to the utility model, the touch head of the touch push rod is in connection with and cooperates with the inclined plane and the step plane of the contact spring so as to realize gradual contact between the contact spring and the first conductive pin, thereby avoiding violent collision therebetween and contact deformation of the two; the tact switch is more reliable to use, and has a longer service life.
