Switch or converter first?

This is very simple yet very confusing. Ill lay it out and make it simple.

[60V Battery] ----- [60V to 12V converter] ----- [On/Off switch] ----- [12V headlight]

OR

[60V Battery] ----- [On/Off switch] ----- [60V to 12V converter] ----- [12V headlight]

Which order would be ideal/Functional/safe? (Basically I do not know whether the switch goes before or after the converter)

NOTE: the On/Off switch is compatible with 12V, 125v, 250v.

Thank you for helping me with this headache.

Is the converter a single purpose?

It is quite possible your converter will burn power even when not in use. So, I'd put the switch between the battery and the converter... Assuming it is only being used for the lights.

If, say you use the converter for multi-purpose (lights, radio, USB charger, etc), then have some kind of ignition switch that disconnects the converter, then have a separate switch after the converter for stuff you want to turn on/off such as the lights.

Note, motorcycles are required to have the headlight, and perhaps taillights on all the time when riding. You may choose daytime running lights (only going through the ignition switch, otherwise on all the time).

If there is an advantage to isolating the converter from the headlight, then have a switch between them along with a switch isolating the battery from the converter. For sure put a switch between the converter and the battery.

CliffordK Its only for headlight. You are right, the switch is like a dam and constantly flooding the converter doesn't seem wise. So Ill put switch between the two. Thanks!

TiHabanero You're right. We surely don't want the converter unnecessarily overheating when not in use.
