Zusammenfassung: | The utility model provides an HXD1C locomotive parking brake button indicating lamp display circuit with an anti-interference function, which comprises an indicating lamp XD, a direct-current power supply and a pressure switch P. The direct-current power supply is a 110V direct-current power supply, one end of the indicating lamp XD is connected with an anode of the direct-current power supply, and the other end of the indicating lamp XD is connected with an anti-interference circuit in series. The anti-interference circuit is composed of a capacitor C and a resistor R which are connected in parallel, and the other end of the anti-interference circuit is connected with the negative electrode of the direct-current power supply through a pressure switch P. By improving an original HXD1C locomotive parking brake button indicating lamp display circuit, on the premise that normal display of a signal lamp is not affected, alternating current signal interference is eliminated, and the running reliability of a locomo |
