DPDT Switch box:

A DPDT (Double Pole Double Throw) switch box is an electrical component used to control two separate circuits simultaneously. It consists of a switch mechanism that can make or break connections for two independent circuits, typically with a common ground or power connection.

The DPDT switch has six terminals: two pairs of input terminals (one for each circuit) and two pairs of output terminals (also one for each circuit). The switch has three positions: one where the input connects to one output, another where it connects to the other output, and a third position where the input is disconnected from both outputs.

This type of switch is commonly used in various applications such as audio equipment, electronic devices, and industrial machinery where you need to switch between two different circuits.
