PURPOSE:To make up a cheap and simple circuit of a flasher by utilizing a relay contact also as a turn switch. CONSTITUTION:If a turn signal control lever 23 is turned in one direction for right turn of a vehicle, a movable member 20a is moved in the arrow direction A. The free end of the first movable contact piece 15a is thereby released in free status from a notch 21a of the movable member 20a so that the first movable contact piece 15a is turned toward the first stationary contact point 16a along with an armature 13a until the contact part 15a' comes into contact with the contact point 16a, on account of which a right flasher lamp 31a is lighted. After a lapse of a certain time from the lighting, electric current is supplied from an oscillation circuit 27 to a coil 11. Then, an iron core 11a attracts the armature 13a, and the contact piece 15a is separated from the contact point 16a to turn out the flasher lamp 31a. After an additional lapse of a certain time, the electric current supply to the coil 11 is cut off so that the contact piece 15a comes into contact with the contact point 16a again to light the lamp 31a. |
