Abstract
The utility model discloses a button-type switch having a protection function. The switch comprises a first spring leaf and a first housing, wherein the first spring leaf is arranged in the first housing. The switch is characterized in that the switch also comprises a second housing and a second spring leaf, wherein the second housing is mounted on the first housing by the second spring leaf. Through a manner that double housing mechanisms are provided with double springs provided by the utility model, switch damage caused by very large contact force is effectively avoided. One end of the second housing is connected with a hinge of the first housing and the other end of the second housing is mounted on the first housing by the second spring leaf, so that a certain angle is formed between the second housing and the first housing. The button has preferable handle when pressed down. The button-type switch is simple in a structure and is very practical.
