High-low beam switching device for a headlight

A high-low beam switching device for a headlight comprising

• a housing having a pivotal section at one end and a semi-cylindrical wire hole at the surface of the lower edge circumferential surface, and having the other end being provided with a base cap seal having a wire-binding hole;
• a seat body for the engagement with a solenoid module of a magnetic coil loop;
• the solenoid module being a wired wheel having a center hole and the edge thereof being surrounded with wires, the interior of the center hole being a securing seat and a sliding rod, and the external side of the end edge being mounted with a pad, and the external of the sliding rod being provided with an elastic body, and a blocking plate being mounted onto a conic end;
• a connection tube seat having a connection section at one end and an engaging section at the other end, and the inner wall therefore being a protruded rib;
• a sliding light tube support being a circular body having a sliding slot provided around the circumferential edge thereof;
• a light tube having a single light point therein, wherein a high and a low wire is extended from the light point;
• and
• a combination seat having a plurality of combination wing at the circumferential edge of the center through hole thereof;
• and
• wherein the surface of the wing is provided with a plurality of combination holes to secure with the light bulb seat for car, thereby the solenoid module produces a magnetic field effect to attract the sliding rod and the securing seat to form as one unit and the sliding tube seat drives the light tube to move backward a distance of 7 mm, and when there is no magnetic field, the elastic body causes the sliding tube seat and the light tube to restore to the original position, therefore, the focus of the single light point is changed to achieve the switching of a high-low beam of the headlight.
