Abstract: PURPOSE:To obtain a cheap flashing device with a simple structure by connecting an elongated drive element made of shape memory alloy and shape-memorized in the longitudinal direction, electrically and mechanically to a snap opening and closing mechanism for a movable contact so as to periodically open and close the movable contact. CONSTITUTION:When a movable contact SW1 in a turn indicator manipulating switch SW is turned from its neutral position so as to close, for example, a right turn indicating stationary contact SWR, a turn indicating lamp FR.RP is turned on. Current runs through a pin 1C, a stationary piece 5C, a drive element 5, a movable contact support member 4, a movable contact 3, a stationary contact 2 and a pin 1D in that order, and accordingly, the drive element 5 reduces its length to a value which is shape-memorized, due to its autogenous heat so that the upper end part of the movable contact support member 4 is pulled leftward and downward, resulting in deformation of the member 4. Then, a movable part 4D of the support member 4 in an arcuated condition is reversed from its convex shape into its concave shape, and accordingly, the movable contact 3 is separated from the stationary contact 2 so as to deenergize the flashing indicating lamp. Further, the drive element 5 is cooled down, and is returned into its original shape. Then, the movable contact 3 is again made into contact with the stationary contact 2, thereby the turn indicator FR.PR is turned on.
