技术说明

Technical description
 
该系列速动开关的一个特点是,由于弹簧预加拉力而使接点桥快速动作。该速动机构使接点通断与传动速度完全无关。
该系列速动开关元件具有强制断开功能,不会产生静接点的粘连,可以应用在对安全要求极高的交通和机械等领域。
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.

开关元件的电寿命是由电路中的电流和电压所决定的,此外还受到负载类型的影响,如感应负载或容性负载。
同时还取决于开关的使用频率。
环境污染程度,如尘埃等都会缩短接点的电寿命。
为提高在较高直流情况下的负载通断能力,我们提供永磁灭弧罩,供您选择。我们的灭弧罩为开关接点提供一个磁场,强迫电弧吹出接点区域。吹弧效果与接线的极性无关。
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.
