Abstract

PURPOSE: To obtain this car speed meter with a variable alarm device that safely drives a car travelling on a roadway by automatically giving alarms when the car exceeds a speed limit on the roadway.
CONSTITUTION: When a car travels on a road in a speed limit 40km/h, speed is set to 45W50km/h by turning a dial 4. The contact pieces of reed switches 15a, 15b are opened when the speed of the car is not more than set value, but a magnet 17 joined on a speed indicating pointer 3 is united with the reed switches and closes the switches when the speed reaches the set speed. Thus, the currents of a battery flow through a buzzer 14 to operate the buzzer, and alarm sounds are emitted to drivers through a buzzer sound window 6.
