CUTOUT DEVICE FOR MARKER LAMP, AND MARKER LAMP DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a repeatedly usable cutout device for a marker lamp hardly causing operational fluctuation; and to provide a marker lamp device capable of being maintained without breaking a constant-current power source by using it.

SOLUTION: This cutout device CO for a marker lamp is connected to a power feed means 22 of the marker lamp C in parallel with the marker lamp C, and is so structured by an electronic circuit as to shunt the feed means 22 in response to a relatively high voltage acting on the feed means 22 when the marker lamp C is separated from the feed means 22 or a lamp 51 of the marker lamp C is not lit; and to cancel and recover the shunt of the feed means 22 in response to a relatively low voltage acting on the feed means 22 when the marker lamp C is connected again or the lamp 51 of the marker lamp C is replaced with a normal one.
