Toggle switches are an invaluable tool for many electricians, engineers and hobbyists and the A203KZQ is a popular choice within the industry. The A203KZQ is a single-pole double-throw (SPDT) toggle switch that is capable of changing the connection between two different circuits.

In terms of application fields, the A203KZQ is mainly used to control the on/off function and switching of low current circuits. It is generally used in lighting applications such as table lamps, night lamps, spotlights, and other interior lighting fixtures. The A203KZQ toggle switch is also suitable for controlling dimmers, fan regulators, or other AC/DC electrical control systems.

The working principle of the A203KZQ is relatively simple. It is a SPDT switch which has two separate circuits: one that turns ON and the other that turns OFF. One of the two circuits is powered and the other is not. When the toggle switch is in ON position, the powered circuit is energized and the other circuit is not. Conversely, when the switch is in OFF position, the powered circuit is not energized and the other circuit is energized instead.

When used in lighting fixtures, the purpose of the A203KZQ is to allow the user to change the connecting path of the light according to their needs. For example, when the user turns the toggle switch to ON position, the light will be connected to the power source. When the user turns the toggle switch to OFF position, the light will be disconnected from the power source. The same principle can be applied to other electrical and electronic components such as motors, dimmers, and regulators.

In summary, the A203KZQ is a single-pole double-throw (SPDT) toggle switch that is mainly used to control the on/off function and switching of low current circuits. Its working principle is based on the two separate circuits (one being energized when in ON position, and the other being energized when in OFF position). As such, the A203KZQ toggle switch is suitable for controlling dimmers, fan regulators, or other AC/DC electrical control systems.
