Research on Switch with Locking Device

for normal switch, knob can rotate with force to different positions which correspond to different output functions. But for some functions, misoperate are not allowed, such as for anti-aircraft light switch on military vehicles, there is light control function for civil vehicles, and also request light control function in air defense mode in combat. This study describes a switch with locking device whose different gear corresponding to different output function and the switch is able to change at will between two or more modes, of which has the function of interlocking and can prevent misoperation. The paper analyzes and discusses from different switch aspects, including automobile electrical appliance, anti-aircraft light switch for military vehicle, the locking device and so on
