Abstract
The present invention relates to an overload protection device of a press type switch in which the switch main body has slide grooves within the bouncing range of the free end of the conductive strip. The shape of the slide grooves is formed by a plurality of slide rails. A push-pull element is pivotably connected to the inside of the press button. A cross bar is fitted to the bottom of the push-pull element while both ends of the cross bar are disposed in the slide grooves. Accordingly, the push-pull element is able to change path and locating position in the slide grooves. Moreover, the conductive strip can be controlled in on/off-state by means of the force in different directions. Beside, the free end of the conductive strip is kept in an independent state so that the conductive strip is transformed into the off-state in case of overload. Consequently, the safety of the user can be ensured.
