What are the PINs and gears for rocker switches?

The foot position and gear position of ship type switches usually vary depending on their design and function. Here are some common types of foot and gear positions:
Single pole single throw (SPST):
Pin position: Usually there are two pins used to control the switch of a circuit.
Single Pole Double Throw (SPDT):
Pin position: Usually there are three pins that can be switched between two circuits.
Bipolar Single Throw (DPST):
Pin position: There are usually four pins that can control the switches of two circuits simultaneously.
Bipolar Double Throw (DPDT):
Pin position: There are usually six pins that can switch between two circuits and control both circuits simultaneously.

On/Off:
The most basic gear has only two states: on and off.
Multiple gears:
Some ship switches may have multiple gears, such as low, medium, and high, suitable for adjusting the power or brightness of electrical appliances.
