PURPOSE: An automatic light switch prevents the instantaneous turning off of a head lamp by realizing a 2nd light section and an auto light section for some interval, synchronously. CONSTITUTION: The positions of terminals(TA,TE,T1,T2) and contact terminals(C1,C2,C3,C4) are predetermined to convert a 2nd light section to an auto light section with maintaining the two states together for some interval. The terminals(TA,TE,T1,T2) are exposed around a circumferential direction. The contact terminals(C1,C2,C3,C4) have 4 contact points around the circumferential direction. On a switch off section, the rotation angles of the contact terminals(C1,C2,C3,C4) are set between 0 deg to 17 deg. On a 1st light section, the rotation angles of the contact terminals(C1,C2,C3,C4) are set between 17 deg to 75 deg. On a 2nd light section, the rotation angles of the contact terminals(C1,C2,C3,C4) are set between 43 deg to 75 deg. On an auto light section, the rotation angles of the contact terminals(C1,C2,C3,C4) are set between 67 deg to 99 deg.
