Rockers Switches – M2023TJW03 Application Field and Working Principle

A rocker switch is described as a momentary contact switch which typically comes in single or double pole type. They are primarily used to isolate parts or components of a system, such as power or data lines, in order to prolong the life of the system. In the context of being a switch, rockers are typically operated manually by the user, although they can also be controlled via an actuator and be automated or remotely operated.

The M2023TJW03 specifically is a single-pole, double-throw (SPDT) rocker switch with an insulating and single-pole switching action. It is rated for 6 Amp at 250 Volts AC and for 12 Amp at 125 Volts AC, so it is excellent for controlling mains electric equipment. The contacts are of Silver (Ag) alloy material and designed for superior contact finger moments as well as superior contact finger life. This switch also has a rocking motion contact system and is sealed to IP30.

Application Fields

M2023TJW03 switches usually have a common contact that is linked either to the normally open contact or to the normally closed contact, depending on the lever\'s position. The common, normally open and normally closed contacts are all available as solder, PCB or screw terminal connections. This means that M2023TJW03 switches, as versatile as they are, can be used in a wide range of applications including electronics, household appliances, manufacturing machinery and industrial automation.

In addition, with the rocking motion contact system, the M2023TJW03 offers snap action, which is a performance that needs to be considered in some safety-critical applications such as elevator systems. This snap action can also be used in applications such as lighting systems where users need to use the switch in order to turn something on/off quickly.

Working Principle

A switch circuit is usually made up of a common, a normally open contact, and a normally closed contact. In the M2023TJW03 switch, when the rocker is moved to the opposite side, the contacts remain in the same position and just show a displacement. This happens due to the use of a plastic or metal centre-piece which is horizontally fixed on the axis. This centrepiece has an electrically neutral polarity and its metallic parts ride in the centre of both the lower and upper terminals.

Consequently, while in the M2023TJW03 switch the common contact is connected to the normally open contact when the rocker is moved to the other side, it is separated from. When the rocker returns to its original position, the state of the contacts remain unchanged and disconnected. This means that the M2023TJW03 switch is a type of momentary contact switch and has a different state in each lever position.

Conclusion

The M2023TJW03 rocker switch is a single-pole, double-throw (SPDT) switch that offers excellent performance even with its basic design. With the rocking action contact system, the M2023TJW03 offers snap action capability, which can be used in a variety of applications to meet user needs. Additionally, its contact finger moments and life are superior to other components in its class, making it a reliable performance choice. With its advantageous characteristics, the M2023TJW03 switch is ideal for use in both general and specialised applications.
