Abstract

The utility model provides a safe slide switch which is mainly provided with a clamping assembly comprising a group of spacing plates and a floating connection part between a group of push buttons and a group of circuit switch assemblies. When a turning button is turned to inclined pushing teeth of the turning button and the floating connection part which mutually push and prop, the floating connection part slides towards the direction of the spacing plates. Moreover, the protruding block of the floating connection part is buckled into the groove of the spacing plates to form the slide limitation of the whole group of the push buttons, and the locking state cannot be switched at random. Moreover, when the turning button is turned to the inclined pushing teeth to form mutual meshing, the floating connection part can be subjected to spring action force so as to retreat the protruding block into the groove space of the spacing plates, and thereby the slide limitation to the whole group of the push buttons can be relieved to recover to the state of switchable operation.
