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*无关。
该系列速动开关具有双断开触点、快速动作机构和强制断开功能。这就保证了常闭触点的可靠打开,即使由于短路或过载原因使触点熔焊,也不会产生接点的粘连。可以应用在安全要求*的交通和机械等领域。
A characteristic feature of the S800 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.
S800 Series switches are from Z SPDT with double-break contactssnap-action mechanism and positive operation which ensure a forced breaking of the normally closed contacts in case of spring failure or once the contacts have become welded together due to the short-circuit. This makes them ideally suited for use in safety demanding field such as transport and machines

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。
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
