A rocker switch of the present invention includes a driving member, a follower, and a driving elastic member. When a button is pressed, the button can push the driving member to rotate, and a lockingmember stops the rotation of the follower. As the driving member rotates, the stationary follower provides a continuous elastic force to the driving elastic member.
