# What does SPDT mean on a toggle switch?

## What does SPDT mean on a toggle switch?

Single Pole Double Throw

A Single Pole Double Throw (SPDT) switch is a switch that only has a single input and can connect to and switch between the 2 outputs. This means it has one input terminal and two output terminals. A Single Pole Double Throw switch can serve a variety of functions in a circuit.

## How many loads can be controlled by the SPDT switch?

Functions like two separate SPDT switches operated by the same actuator. Only two loads can be On at a time.

**How many amps can a toggle switch handle?**

These toggle switches are quality built and can switch up to 20 amps of current at 12 volts DC or 120 volts AC.

### Is there a 30 Amp switch?

Leviton 30 Amp Industrial Double Pole Switch, White-R62-03032-2WS – The Home Depot.

### What is difference between SPDT and DPDT switch?

SPDT vs DPDT The difference between SPDT and DPDT is that SPDT has a single input that connects to two outputs while the DPDT has two SPDT integrated together which enables it to control two circuits together at the same time.

**What does SPDT and DPDT mean?**

The difference between SPDT and DPDT is that “SPDT” stands for “single pole double throw” while “DPDT” stands for “double pole double throw.” Both terms are associated with and are varieties of switches. A pole refers to the number of circuits or wires that a switch will control.

## Is a 30 A double 15?

This shows that each leg of 30 amp double breaker delivers 30 amps, and not 15 amps. . If a 30 amp double pole breaker was 15 amps on each leg, then a 20 amp double breaker would be 10 amps on each leg. And a 15 amp double breaker would be 7.5 amps on each leg.

## What does 250vac mean?

So, in the example below the maximum amp rating for this switch at 250 volts AC (VAC) is 10 amps; the maximum amp rating at 125 volts AC for the same switch is 15 amps. This rating reflects the amount of current the switch contacts can handle at the moment the device is turned on.

**Can you use a 30 amp switch on a 20 amp circuit?**

When it says 30 amps it means it can go up to 30 amps. If it is a fused disconnect it will hold up to 30 amp fuses. If it has fuses just use 20 amp fuses, they will work as they are supposed to. Size the wires appropriately, usually 12 gauge for a 20 amp circuit and use a 20 amp circuit breaker.
