Toggle Switches: 2TW1-70 Application Field and Working Principle

Two-wafer, single-pole, double-throw toggle switches are widely used in many different applications. In this article, we will examine the application field and working principle of the 2TW1-70 variation.

Application Field

The 2TW1-70 toggle switch is most often used in electric notations, as it is well suited for controlling an application using a single pole. These are widely used in fields such as automotive, HVAC, appliances, GPS units, home electronics, marine, electric power tools and medical equipment.

The 2TW1-70 can be used in a variety of applications that require switching from one circuit to another. These include the control of low-voltage DC currents, the control of high-voltage AC currents, and the control of power in industrial applications. As the switch is all-weather sealed, it can be used in extreme environments and is highly resistant to water and dust ingress.

The switch is also extremely durable, being capable of operating up to 10 million cycles, while its high-temperature construction ensures that it can withstand up to 130°C.

Working Principle

The 2TW1-70 is a double-throw switch,meaning it has two separate poles that can be used to switch different circuits on and off. The switch is operated by pressing the switch head down. When pressed, the current is diverted through the top pole, thus turning the circuit on. To turn the circuit off, the switch head is pressed again and the current passes through the bottom pole thus turning the circuit off.

The 2TW1-70 switch uses a two wafer construction, meaning it is constructed from two separate wafers that are connected by a shorting bar. This shorting bar is responsible for closing one pole as the other is opened, allowing the switch to be operated without the need for an additional input (+ve) pole.

The switch also features a built-in ratchet mechanism, ensuring the switch is held in place regardless of vibration or shock. This ensures that the circuit remains off until the switch is pressed again.

The 2TW1-70 switch also features a built-in internal arc chamber. This chamber, which is constructed from highly conductive silver, is designed to quell any electrical arcing when the switch is operated. This ensures that the switch is able to operate safely and efficiently.

Conclusion

The 2TW1-70 toggle switch is a highly versatile switching device, able to be used in a variety of applications. With its all-weather sealed construction, durability and built-in ratchet and arc chamber, the switch is both reliable and safe. As such, it is an excellent choice for a variety of switching needs.
