Introduction

Rocker switches are automatic control devices which are used to switch on and off electric circuits with ease. They are a form of low-current-carrying switches that have a pivoting lever or rocker arm to turn on and off a circuit. They are usually operated automatically and electronically, with a motor-driven, push-button, rocker-arm mechanism.

History

Rocker switches were developed in the early nineteenth century by the invention of lever-type actuators. These electro-mechanical control systems were used to automatically and remotely switch-on and switch-off electric appliances such as fans, lights, and electric motors. In the mid-twentieth century, these switches were enhanced with the development of motor-driven, push-button and rocker-arm actuators and relays which allowed electrical appliances to be turned on and off by simply pushing the rocker arms.

Design and Mechanism

The 6-1571986-4 rocker switch is a momentary type switch which is used to turn on and off the power to an electrical circuit. It consists of 3 basic components: a pivot arm, a switch mechanism, and an electric contact point. The pivot arm is connected to the switch mechanism by an axis and is used to move the contact point from the OFF to the ON positions. The switch mechanism is located within the pivot arm and is spring-loaded, so that when the pivot arm is actuated, it will return to its original position when the circuit is opened.

Application Field and Working Principle

Rocker switches are mainly used for residential and commercial applications. They are usually used to switch on and off power to numerous electrical appliances and devices such as lights, fans, electric motors, pumps and more. The 6-1571986-4 rocker switch is rated for 20A at 277VAC and has two circuits, one for common and one for normally-open.To control the power supply of the 6-1571986-4, the user is only required to manually rock the pivot arm to the ON or OFF position. The switch mechanism will then move the contact point to the corresponding position. When in the OFF position, the contact point is open and the circuit is broken; when in the ON position, the contact point will close, completing the circuit and turning on the electrical device.

Advantages

Rocker switches have several advantages compared to other types of switches. They are easy to use and require minimal effort when actuating, as they require only a light rocking of the pivot arm in order to change positions. They are also very reliable and require no maintenance, as their spring-loaded mechanism automatically returns to the OFF position when the circuit is broken. And because they are relatively inexpensive to manufacture, they are often found in applications where cost is an important factor.

Conclusion

The 6-1571986-4 rocker switch is a reliable, low-cost control device which is used to switch on and off electrical appliances and devices. It is composed of a pivot arm, switch mechanism and an electric contact point and is usually rated for 20A at 277VAC. The user simply needs to rock the pivot arm to the ON or OFF position in order to control the power supply. This type of switch has several advantages due to its low cost, reliability and ease-of-use.
