摘　　要：对集成电路式静态继电器整定常用的0～9码开关、8421码(BCD码)开关、05码等数字拨盘开关接点转换示意图进行了介绍,分析了数字开关因自身的结构原理在接入电路后易发生的故障,再根据数字开关接入电路后可能发生的故障,探讨了静态继电器测试点的合理选择方式。The contact points change - over schematic diagrams of digital dialing switches of 0 ~ 9 code, 8421 code and 0. 5 code, ate, commonly used for calibration of static relays of integrated circuit type are presented , and the rational selection of static relay test points is discussed by analysing the failures which can easily occur after the digital switches being led in the circuit for its own structural reason.
