Will a 12v switch work on 24v?

No, you can’t, you need to respect both the maximum voltage (when the switch in open) and the maximum current (when the switch is closed).

What is DC on a rocker switch?

Alternating current (ac) or direct current (dc) circuits are capable of carrying very different currents, as illustrated by the ratings on the switch in Figure 1. This is why it’s so important for designers and engineers to understand how to pick the right switch for their product. 1.

How many amps can a rocker switch hold?

Full size rocker switches are higher power rocker switches capable of switching up to 21 amps at 12 volts DC.

What is the difference between a rocker switch and a toggle switch?

Operation. Both rocker switches and toggle switches operate in the same way, as they both have a regular on/off function. Toggle switches do, however tend to offer a slightly louder “click” sound when switched on or off, compared to rocker switches.

Can you use an AC toggle switch for DC?

DC does not so the switch has to survive until the arc dies down on its own. So the DC switch has to be hardier and will therefore work with AC. However, the AC switch is not as hardy and should not be used with DC.

Can I use an AC rocker switch for DC?

Are switches rated for AC or DC?

The first thing you need to know is that light switches are rated based on the electrical current type. For example, the two most common types of lighting switches are DC (direct current) and AC (alternating current).

How much voltage can a switch handle?

DC Rule of Thumb This “rule” states the highest amperage on the switch should perform satisfactorily up to 30 volts DC. For example, a switch which is rated at 10A 250VAC; 15A 125VAC; 3/4HP 125-250VAC, will be likely to perform satisfactorily at 15 amps up to 30 volts DC (VDC).

How many volts can a switch handle?

The rule states the highest amperage on the switch should work up to 30 volts DC. A switch which is rated at 10A 250VAC; 15A 125VAC; 1/3HP 125-250VAC will perform well at 15 Amps up to 30VDC.

Why would you use a rocker switch?

Rocker switches are used in surge protector s, display monitors, computer power supplies, and many other devices and applications. A rocker switch with independent circuitry can have a light activated on the face of the switch in both the on and off positions, which allows the switch to be found easily in the dark.

Can you use a light switch for DC?

Typical house switches are not rated for DC. When you break the DC circuit it’s much harder to extinguish the arc. An AC arc extinguishes itself 120 times per second, DC does not. Using AC switches will work but the contacts will wear quickly and you will have to replace the swithces often.
