According to the switching device with the circuit turn-on of the rotation control stop lamp of the pedal arm of the motion interlock of brake pedal is well-known.The push rod that this switching device has not the connector that rotates along with pedal arm and rotates along with this pedal arm.In this switching device, push rod is when moving with respect to connector, and along with moving of push rod, the bonder terminal in moving contact point and being fixed on connector contacts, separates, thus the conducting of control circuit.
The contact-making surface of the general contact point of switching device in the past is relatively slicker and more sly, and, near some silicon (Si) particle that suspended of two contact points.When two contact points were close, small electric arc took place between two contact points.These electric arcs can produce suction-operated to the silicon particle, make it be deposited in the contact point surface, because the effect generation oxidation of Joule heat generates one deck dielectric oxide film.
When making the electricity consumption ball as stop lamp, because the impulse current that rated current is 5～15 times flows into suddenly, although the contact point surface has generated dielectric oxide film, take place between two contact points to destroy and to remove the arc discharge of this oxide-film, thereby guarantee the conducting of power supply and stop lamp.
Along with reducing going deep into of power consumption viewpoint, LED is popularized on market gradually as the situation of stop lamp.Because LED does not need big electric current, so when using LED as stop lamp, there is not impulse current to flow into, also just can not destroy dielectric oxide film, thereby cause to guarantee the conducting of brake light circuit, even that is to say and stepped on brake pedal, stop lamp might not work yet.
Therefore, adopting under the situation of LED as stop lamp, people have adopted the surperficial roughening that makes each contact point in the switching device, the scheme that forms a large amount of jogs.Can improve the probability that exists that is not insulated protuberance that oxide-film covers like this, cover even some protuberance is insulated oxide-film, by be not insulated the protuberance that oxide-film covers and contact, also can guarantee the conducting of brake light circuit.And the protuberance that is insulated the oxide-film covering is owing to constantly repeat contact, and oxide-film is rubbed off, and the conducting of circuit is restored.
In recent years, multipurpose sport car SUV was well received on market, and the occasion of multipurpose sport car breakdown trailer is many, and this trailer is the same with the multipurpose sport car, also is provided with stop lamp.The stop lamp of multipurpose sport car as mentioned above, many is adopts LED, and trailer adopts electric ball as stop lamp mostly.
Control the LED stop lamp of multipurpose sport car with the switching device of above-mentioned LED, during the circuit turn-on of the power supply that carries at the electric ball stop lamp and the multipurpose sport car of trailer, when impulse current flows into each contact point, the surperficial a large amount of jog that forms of each contact point is melted.This causes each contact point surface to polish, and what be not insulated protuberance that oxide-film covers exists almost vanishing of probability.After this, when trailer when the multipurpose sport car disconnects traction, do not have impulse current to flow into each contact point, can not destroy each contact point surface film oxide.Therefore, although step on brake pedal, the stop lamp of trailer is possible can not be bright.In other words, the reliability aspect circuit turn-on is lower.
