Headlight Switch for cars with Console Gauges

[ZLP955]

Just saw THIS listing for a Delco Remy headlight switch, part # 1995173, stated as being for cars with console gauges. I was not previously aware that console gauges required a different type of headlight switch, and would appreciate it if someone knowledgeable could explain what the difference is between switches for cars with, and without, console gauges.
