  • Flasher switch with a mechanical music mechanism
    Patent number: 5521321
    Abstract: The present invention is a new design using a mechanical musical structure to serve a flasher switch. It consists of a base, a musical scale device, a triggering device, a driver and a flasher switch. The above-described devices are installed on the base. When the driver drives the triggering device to rotate, the convex points on the metal tubing of the triggering device would rotate and touch the musical scale rods of the musical scale device. Due to intermittent contact between the musical scale rods and the convex points, the device releases music and triggers the switch to serve a flasher.
