15 AMP 2 Way Toggle Switch
The double-pole switch is commonly used in industrial applications but can be found in some home wiring systems. Like the single-pole switch, a double-pole has ON and OFF markings and controls a device or equipment from one location. The main difference is that a double-pole switch has four brass hot terminals (instead of two), plus a ground, allowing you to connect it to two pairs of hot wires from a 240-volt circuit.
Double-pole switches are commonly rated for 30 amps (compared to 15 or 20 amps with standard switches) so they can control higher-demand appliances, motors, and machinery.
