技術說明
Technical description
該系列速動開關的一個特點是,由于彈簧預加拉力而使接點橋快速動作。該速動機構使接點通斷與傳動速度*無關。
該系列速動開關元件具有強制斷開功能,不會產生靜接點的粘連,可以應用在對安全要求*的交通和機械等領域。
A characteristic feature of the S826 Series switch is the rapid motion of its contact bridge induced by the force of a pre-tensioned spring. This snap-action mechanism makes the connection and opening of contacts to be independent of the actuating speed.
The positive opening operation of S826 series snap-action switches guarantees the forced disconnection of contacts even when stuck or welded due to overload currents of in the unlikely event of a failure of the snap-action mechanism, therefore, they are suited for safety-related applications such as transport and machine filed.

開關元件的電壽命是由電路中的電流和電壓所決定的,此外還受到負載類型的影響,如感應負載或容性負載。
同時還取決于開關的使用頻率。
環境污染程度,如塵埃等都會縮短接點的電壽命。
為提高在較高直流情況下的負載通斷能力,我們提供永磁滅弧罩,供您選擇。我們的滅弧罩為開關接點提供一個磁場,強迫電弧吹出接點區域。吹弧效果與接線的極性無關。
The electrical life of switching elements depends on the current and voltage in circuit, as well as the type of load such as inductive and capacitive load, and it also depends on the operating frequency.
The levels of environment pollution such as dust will also shorten the electrical life of contacts.
To increase the breaking capacity and the permissible breaking current under DC loads, integral magnetic blows-out are available. Permanent magnets create a field across the switching contacts, forcing the arc out of the contact area
The blowout magnets are mounted in the cut-outs of the contact area, the effect being independent of the terminal polarity.
