description The utility model discloses an anti-electromagnetic interference state indicating lamp circuit, which comprises a resistor R1, an electronic relay, a state indicating lamp, a resistor R2 and an MOS (Metal Oxide Semiconductor) switching tube which are sequentially connected between a working power supply and a grounding end, the control end of the electronic relay and the control end of the MOS switching tube are respectively connected with a control circuit which controls the electronic relay and the MOS switching tube to be switched on and off simultaneously according to a state input signal so as to switch on and off the state indicating lamp, and the power input end of the control circuit is connected with a 5V direct-current power supply. Conduction interference passing through a power line of the state indicating lamp is blocked, and the working state of state indication is effectively stabilized. 本实用新型公开了一种抗电磁干扰状态指示灯电路，包括有顺次连接在工作电源与接地端之间的电阻R1、电子继电器、状态指示灯、电阻R2、MOS开关管，电子继电器控制端、MOS开关管控制端分别连接有根据状态输入信号控制电子继电
