摘要： This invention discloses a rocker switch which provides a reliable movement and a heat-resistant rocker switch by redesigning the position holding mechanism. The rocker switch of the invention comprises: a common contact point, a close circuit contact point, a movable contact point permanently coupled to the common contact point, a rocking switch connecting to the movable contact point and rocking between a close circuit position and an open circuit position, and a position holding mechanism having a spring and an extension rod coupled to one end of the spring. The extension rod is used to change the position of the force acting between the spring and the rocking button and the force acting on the spring in order to improve the life of the spring and increase heat resistance.
