安全继电器是由数个继电器与电路组合而成，为的是要能互补彼此的异常缺陷，达到正确且低误动作的继电器完整功能，使其失误和失效值愈低，安全因素则愈高。

因此需要设计出多种安全继电器以保护不同等级机械，主要目标在保护暴露在不同等级之危险性的机械操作人员。

安全继电器具有强制导向接点结构，万一发生接点熔结现象时也能确保安全，这一点同一般继电器完全不同。安全继电器并不是“没有故障的继电器”，而是发生故障时做出有规则的动作，它具有强制导向接点结构，因此其安全性能较高。

The safety relay is composed of several relays and circuits, in order to complement each other's abnormal defects, to achieve the correct and low error operation of the complete function of the relay, so that the lower the error and failure value, the higher the safety factor.

Therefore, it is necessary to design a variety of safety relays to protect different grades of machinery, and the main goal is to protect machinery operators exposed to different levels of risk.

The safety relay has a forced guide contact structure, which can ensure safety in case of contact melting phenomenon, which is completely different from the general relay. Safety relay is not a "no fault relay", but a regular action when the fault occurs, it has a forced guide contact structure, so its safety performance is high.
