Why would you "normally" use a SPDT switch for the circuit I posted? Every switch has its place. I'm not using a light-up switch or anything that requires power.Although the circuit is drawing a SPST switch, but usually we using a SPDT switch.

That's a good point. Although I didn't find buying my switches very hard. Maybe it's different in Taiwan.There are two reasons.
The first is that the price is similar or equal, and the second is that the 2 pins switch is not easy to buy.
When I using the 3 pins switch, if only two pins is needed then just left the other unused pin and don't care about it, maybe just soldering some solder on the unused pin.
There is another reason that I don't need too much classification of parts, as that I bought 1N4007 to replace all of 1N4001~1N4006.That's a good point. Although I didn't find buying my switches very hard. Maybe it's different in Taiwan.
440 watts is not so high, but 37A is a high current, although it just only 12V.I see.
One more question:
Can you recommend switches that are especially durable? I'm making a light for my photography studio. It uses 8x 55watt bulbs at 12 VDC and I want to use a switch to turn it on... can any switch do that? Do I need a 440 watt (8*55)-rated switch? Do I need a 37amp-rated switch?
Thanks,

Well, it's complicated.... However, it isn't considered nice to use a circuit breaker for a switch...
Especially not an AC rated breaker instead of a DC switch, they are just not meant to do that.But in lieu of such a marking don't use a breaker as a switch.
