Introduction

The JWL21BA1A-A rocker switch is a miniature, snap-in type rocker switch, ideal for use in low-voltage applications. It is simple to mount and can be easily integrated into any existing system. The JWL21BA1A-A rocker switch has a variety of functions and is well-suited for applications such as signal control, industrial and transportation control, power supply and distribution, and more.

Applications

The JWL21BA1A-A rocker switch can be used in a wide variety of applications, including signal control, industrial and transportation control, power supply and distribution, and more. The switch can be used for on/off control, momentary pulsing, or latching operations. With its compact size and easy mounting, the JWL21BA1A-A is particularly well-suited for use in tight spaces, such as within machinery.

Working Principle

The JWL21BA1A-A rocker switch operates using a simple mechanism consisting of an enclosed rocker arm, operated by the user’s thumb or finger. When the switch is flipped up, a set of contacts inside the switch assembly connect to an electrical circuit, causing an action to occur. Depending on the type of connections made, the switch may be used for on/off control, momentary pulsing, or latching operations. When the switch is flipped down, the contacts in the assembly disconnect, and the action stops.

Design and Construction

The JWL21BA1A-A rocker switch is constructed with a thermoplastic outer casing, with four mounting barrels located in the corners of the assembly. The rocker arm is made of highly-durable nickel-plated steel, and the electrical contacts are made of silver-alloy. The switch is designed to be both durable and reliable, withstanding temperatures up to 105°C (221°F).

Considerations

The JWL21BA1A-A rocker switch can provide a useful and reliable solution for many simple and complex applications. However, before making a purchase, buyers should consider the applications for which the switch is intended and know the exact operating characteristics and requirements necessary for the desired operation. It is also important to keep in mind the environmental factors under which the switch will likely be operating, such as heat and vibration, and ensure that the switch is rated for those conditions.

Conclusion

The JWL21BA1A-A rocker switch is a miniature, snap-in type rocker switch which provides simple and reliable operation in a variety of applications. It is designed to be both durable and reliable, withstanding temperatures up to 105°C (221°F). However, before using the switch, buyers should ensure they are knowledgeable regarding the application and environment, as these factors can affect the performance and lifespan of the switch.
