Comprise that also one is positioned at the switch block of described switch cavity, described switch block is provided with contact and tactile spring; Described contact is provided with right to the first corresponding moving contact with described first fixed contact, and described tactile spring is provided with right to corresponding movable palping foot with described second fixed contact;
The upper surface of described switch block is provided with upwardly extending press handle, and described press handle passes the upper surface of described housing;
Also be provided with a vertical induction rod on the lower surface of described switch block, be with a stage clip on the described induction rod;
The front of described pedestal is provided with an induction shell fragment, and described induction shell fragment is over against described induction rod, and the upper end of described stage clip withstands on the described switch block, and the lower end of described stage clip withstands on the described induction shell fragment;
Described first moving contact pair and first fixed contact between distance and described movable palping foot pair and second fixed contact between distance smaller or equal to the distance between described induction rod and the described induction shell fragment.
Further, described induction shell fragment comprises lamellar body, and the middle part of described lamellar body has the convex arc section that is bent upwards, and described convex arc section is over against described induction rod.
Further, described first fixed contact to and second fixed contact between separated by a dividing plate; The central authorities of described dividing plate are provided with the slide plate that thickness is thinner than other parts, and described switch block is provided with the chute suitable with the thickness of described slide plate, and described slide plate inserts in the described chute.
The utility model in use, and is the same with existing double control switch, and press handle is when pressing down, and switch block presses down, and first moving contact pair and first fixed contact to touching, reach the effect of connecting the diplopore switch to touching, movable palping foot pair and second fixed contact.
Simultaneously, when switch block pressed down, induction rod also pressed down, and induction rod is pressed onto induction both can obtain an operating handle during shell fragment, informed that operator's switch connects.
The beneficial effects of the utility model are: be provided with a mechanism that can obtain operating handle separately, can not have influence on first fixed contact in the operating process to right with second fixed contact, therefore can increase the service life, even this mechanism that can obtain operating handle damages, also not influence the use of switch.
