摘要： PURPOSE: To greatly reduce manufacturing cost and to improve operation reliability. CONSTITUTION: A plurality of conductive plates 64 constituting the driving circuit of an electromagnetic relay 4A are press-shaped from a piece of a metal plate and these conductive plates 64 are buried in a resin base 5. Several ends of the conductive plates 64 are protruded in a connector housing 51 integrally formed in the base 5 as connector terminals 641, part of the plate surface of each conductive plate 64 is exposed from the base 5 in a proper location, the proper portions of these plate surfaces are used as fixed contact points for a switching means 3 and circuit elements constituting the driving circuit, the relay coil of the electromagnetic relay 4A, etc., are connected to the other parts.

摘要： PURPOSE:To facilitate the adjustment of the gap between contacts in a relay by providing such an arrangement that an armature plate for striking a diaphragm in the relay is adapted to strike a contact independent from the plate so as to actuate a movable contact on a contact spring. CONSTITUTION:When a winker key switch 64 is turned to, for example, the left in such a condition that a key switch 62 is closed, a current coil 24 is energized through a normally closed contact 80 in a relay so that a contact spring 23 is displaced by means of an armature plate 41 so as to open the normally closed contact 80. This opened condition is sustained during the period of charge of a capacitor 31. When the capacitor 31 is charged, the exciting force of the current coil 24 and a voltage coil 25 is decreased so that the above- mentioned plate 41 is returned toward a diaphragm 3 which is therefore struck by the plate 41. Simultaneously, the normally closed contact 80 is closed to allow the capacitor 31 to be discharged, and accordingly, the voltage coil 25 is energized in the reverse direction, so that the a left turn signal lamp 65 is turned on through the normally closed contact 80.

摘要： PURPOSE:To prevent chattering phenomenon in contact by connecting a bypass means, which is conducted when a voltage drop value, generated in a current oil, increases to a preset value or more, in parallel with the current coil of a relay in a flasher circuit. CONSTITUTION:When a selector switch 4 is closed to either right or left, an electric current is allowed to flow in lamps L in either right or left, but by the magnetomotive force of a current coil 6, a normally closed contact 71 of a relay 7 is opened. While simultaneously charging a capacitor 8, by this charging current, the magnetomotive force is generated in a voltage oil 9, holding the normally closed contact 71 to be opened. Next, decreasing the charging current, when the normally closed contact 71 is closed, a lamp current is allowed to flow in the current coil 6, and the lamp L is intermittently turned on by discharging the capacitor 8. Generating a voltage drop in the current coil 6, when a value of the voltage drop reaches the conduction voltage of a diode 10 serving as the bypass means, the diode 10 is conducted, preventing the generation of excessively large magnetomotive force in the current coil 6.
