It has a DOUBLE pole snap action switch so there would be no arcs on DC.
With any voltage greater than about 15V per contact in series, you will always have an arc to deal with, so you need some means to extinguish it.
With AC and not that high currents (not much above 20A) it is straight simple: The inherent zero crossing uses to be just enough.
For higher currents (e.g. fault currents to be interrupted by a circuit breaker) and/or DC you need really designed in arc quenching mechanism. The lower the voltage and lower the current, the easier it becomes.
E.g. for an automotive environment up to 24V battery you suffice with single contacts, they just need some heat hardening. Higher battery voltages (up to 60V or so) need double contacts (two contacts in series - e.g. two fixed contact terminals, with a moving bridge in a relay), which is obviously more expensive.
That is the main reason, why larger road vehicles, as well as e.g. aircrafts use 24V (28V when charging) battery systems and why higher voltage levels (e.g. PowerNet42V system proposed for cars in early 2000's, today the proposed system is 48V) are long time not that much spread around.
Larger voltages up to e.g. 120V you may get away with just larger distances between contacts (that means higher operating forces, higher consumption of the control electromagnets in relais,...).
Higher voltages than about 120V need really dedicated arc quenching structures (arc blowing magnets, quenching traps,...). These may be incorporated into seemingly plain switch and be very easy to overlook (if you dont know, what features to look for; for 120V just a bit prolonged pieces of metal behind the main contact will quite efficiently suck the arc from the contacts and prolong it so it is not able to hold on), but they must be there.
