Looking for 48v dc light switch

[wpns]

update, i think i found solution. since my plan all along was to string together 12v led strips for a total of 48v, i could wire the switch in the middle so that it will be at 24v. that would allow me to use common off the shelf [aka amazon] switches since many are rated at 24v usually at 5 amp.

Neither of those assumptions are true.

Unless the startup and operating currents are identical, the voltage across the strips will be different. Depending on the mismatch and voltage response, you could have interesting failure modes. Test this and measure voltages!

When the switch is off, there will be 48V across it, no matter where you put it in the series circuit. You might as well say you can switch the ground lead because the voltage is zero.

possibly there might be 48v at start up but at the half way point it will 24v, which is fine.

Just my 2Cents:

ANY Household Light Switches, which are made for 240V AC can switch at the same Ampere rating DC with 12V, 24V and 48V.

12 and 24v maybe. 48v is arcy sparky time.

You are over thing and under thinking this. The differential voltage will be the same no matter where you put the switch. If those string lights are just the resistor and LED type in series, the differential voltage will be less than 20V.

Even under the incredibly low amp draw of a few LED lights?

Snap switches arc/spark when switching 120V circuits as well.

At the end of the day, I still can't understand all the hypothesizing and poo-pooing and predictions of impending disaster when one can test and experiment for less than $2.00 and less than 15 minutes of time.

Because electricity is just magic to 99% of the people here and they just regurgitate what someone else has said.

For things that go arc in the night, get the bible on such things, Gaseous Conductors by James Dillon Cobine.

That is probably my most referenced book.

For 1/120th of a second.

Try it. Maybe it will not hold an arc. My wall switch did but I was switching 3A at 44V over about 5 feet of wire and resistive load.
