Rocker switches are mechanical devices used to control the flow of electrical current in a system. The 2TP118-7 is one such device, designed to meet the needs of a variety of applications. By understanding the application field and working principle of the 2TP118-7, users can make an informed decision when selecting a rocker switch for their particular needs.

2TP118-7 Application Field

The 2TP118-7 rocker switch is designed for use in a range of residential, commercial, and industrial applications. It is most commonly used in lighting, HVAC, and generator control systems. It is also suited for use in motors, pumps, and other electrical devices. The switch is UL and CSA approved for safe operation in most installations.

The 2TP118-7 is rated for up to 20 amps and 250 volts AC, making it suitable for a variety of applications. It also meets NEMA standards and has a UL94V0 flame rating. The switch is available in either single or double throw configurations, allowing for a variety of configurations.

2TP118-7 Working Principle

The 2TP118-7 is a basic rocker switch that operates by interrupting the flow of electrical current between two points. It consists of a metal cam, which is connected to a base plate. This base plate is then connected to a metal lever assembly, which houses two terminal positions. As the lever is moved, the metal cam rotates, breaking contact with one of the two terminals and closing contact with the other. This allows electrical current to flow between the two terminals, while interrupting the current when the lever is in the off position.

The switch also has a mechanical spring-return feature, which will return the lever to the off position after being released. This ensures consistent and reliable operation of the switch. To make installation and maintenance easier, the 2TP118-7 also features screw terminals for connecting to electrical wires.

The switch also features a mechanical switch break, which allows it to be configured in either a double or single throw configuration. In a double throw configuration, the switch will allow for one terminal to be open and the other to be closed. In a single throw configuration, the switch will allow for both terminals to be open or closed simultaneously.

Conclusion

The 2TP118-7 is a versatile rocker switch that is suitable for use in a variety of applications. By taking into account the application field and working principle of the 2TP118-7, users can make an informed decision when selecting a rocker switch for their specific needs.
