Abstract

An unforgettable interlocked light switch of automobiles has its key handle (3) located near the engine ignition switch (1) such that the ignition key handle (2) will interfere with (3) and the ignition key cannot be withdrawn if all lights are on. The ignition key can be withdrawn if only emergency lights are on, or if all lights are off.

Description

Unforgettable Interlocked Light Switch of Automobiles TECHNICAL FIELD

This invention relates to an unforgettable interlocked light switch of automobiles. The light switch has to be turned off before the engine ignition key of the automobile can be withdrawn.

BACKGROUND ART

In order to remind myself to turn off the lights before leaving my car, I once installed a small tumbler switch near the keyhole of engine ignition switch such that the tumbler. handle is turned to the area of the withdrawn position of the ignition, key when the lights are turned on and when the engine is running such that the tumbler handle has to be turned back and the lights are turned off consequently when I want to leave the car with the key. The tumbler switch did not have enough capacity to carry the electric current of the lights. So, it was not electrically connected to the circuit of lights, but instead served as a reminder only. It is easier for me to remember to turn the position of the tumbler handle whenever I turn, on the lights than to remember to turn off the lights when I leave the car. Obviously the tumbler switch can be used to switch on an electric relay of enough capacity to switch on the lights indirectly. A small tumbler switch can be glued onto the surface near the keyhole of the ignition switch for retrofitting an existing car.

For a new car the best embodiment would be as follows.

BRIEF DESCRIPTION OF DRAWINGS An embodiment of the invention will now be described, by way of example, with reference to the accompanying drawings, in which:

Figure 1 is the front view of the arrangement of parts comprising rotary ignition switch 1, ignition key handle 2, and the knob (or handle) of sliding light switch 3, and Figure 1A is the profile. EMBODIMENTS OF THE INVENTION

As shown in Figure 1, the withdrawn position of key handle 2 is 21 which will interfere with knob 3 if the top side of 3 is at its extreme outward position 33 (Figure 1A) when all lights are on. Thus key 2 cannot be withdrawn unless the top side of 3 is pushed inward to position 32 when the head lights are,off and only the emergency lights are on or to position. 31 when all the lights are off.

Claims

CLAIMS 1. A method of reminding the driver of an automobile to turnoff the lights before leavingythe automobile by locating the knob (or the handle) of the switch of lights at the vicinity of the keyhole of engine ignition switch such that the knob of the switch of lights will prevent the ignition key to be turned to its withdrawn position, when all lights are on and the ignition key can be drawn out of the keyhole only if the knob of the switch of lights is moved to the position of only emergency lights being on or to the position of all lights being off.
