Mechanical control type non-contact ultraviolet lamp tube timing switch

The utility model relates to a mechanical switch, in particular to a mechanical control type non-contact ultraviolet lamp tube timing switch, which is characterized in that a movable disc is arranged in an accommodating cavity, the movable disc is matched with a speed reduction driving structure through a clutch structure, a circuit module is arranged in the accommodating cavity, a rotating ring is arranged at the upper part of the movable disc, and a shifting button is fixedly arranged at the edge of the rotating ring; a telescopic trigger switch is mounted on the circuit module; the trigger switch is connected in series with the ultraviolet lamp tube and the deceleration driving structure through the circuit module. The trigger stroke is adjusted in a mechanical control mode, then the timing effect is achieved, and compared with control of combining a circuit module with a timer, the mechanical control mode has the advantages of being low in manufacturing cost and maintenance cost and long in service life;
