Rocker Switches - M2019TZW13 Application Field and Working Principle

The M2019TZW13 rocker switch, also known as the two-wave three-position rocker switch, is a common type of switch found in control systems. It is usually used to control the speed of electric motors, and is also regarded to be a reliable type of switch in applications that require short engagement times, minimal contact disturbance and low contact pressure. Such applications include, but are not limited to, AC motors, wind turbines and high-power equipment.

Structure

The M2019TZW13 rocker switch consists of a two-part contact, three-position handle, two-level switch combination, two individual terminals and two pieces of connecting wires. The two-part contact is responsible for connecting the two switch terminals to the electric motor. It consists of a stationary contact, which is connected to a spring and a small piece of metal which moves with the handle. The two-level switch combination comprises of two individual switches - one for the ‘on’ position, and one for the ‘off’ position.

Working Principle

The M2019TZW13 rocker switch is based on the basic principle of a single-pole switch. When the handle is moved to the ‘on’ position, the stationary contact will be connected to the metal piece which moves with the handle, allowing current to flow to the motor. In the ‘off’ position, the metal piece will be disconnected from the stationary contact, thus prohibiting any current from flowing to the motor. When the handle is moved to the ‘light’ position, the stationary contact is connected to a coil within the handle, allowing a small amount of current to flow to the motor, thus controlling its speed.

Application Field

The M2019TZW13 rocker switch is typically used to control the speed of electric motors in a variety of applications. Such applications include, but are not limited to, industrial machinery, HVAC equipment, medical and laboratory equipment, home appliances, and automotive components. Moreover, the switch is also used in low voltage power distribution networks, as well as in a wide range of electric power control circuits.

Conclusion

The M2019TZW13 rocker switch is a reliable type of switch that is used widely in the control systems of electric motors. With its two-way three-position handle, it allows for great flexibility and accuracy in controlling the speed of an electric motor. Moreover, its two-level switch combination and two individual terminals allow for a safe and secure engagement process. Overall, the M2019TZW13 is an ideal choice when it comes to controlling the speed of electric motors in a variety of applications.
