ABSTRACT:
A safety switch control structure for a lamp device, including outer mask shell for lamp device, lamp mask, fixing rack and interlock, wherein the fixing rack installed underneath the lamp device outer mask shell is equipped with interlock, the interlock is underneath the socket, above the interlock is installed with a spring piece, and a switch is underneath the spring piece, and the spring piece lock of interlock is underneath one of the spring clips; furthermore, the spring piece protruding part is underneath the clip part of the spring clip end. When the lamp mask is combined with the socket, the open spring clip on the socket lets the interlock contact socket and forms a conducting channel. When the lamp mask is separated from the socket, the spring clip goes back to its original shape and no longer contacts the spring piece of the interlock; no electricity is passing.
