Rocker switches are some of the most common on/off switches in the world. They are used in numerous applications from household electronics to heavier-duty industrial applications. The JWM21BA2A-B Rocker Switch is a great example of a small-scale rocker switch and is suitable for a large number of applications.

Design

This rocker switch is a SPST (single pole, single throw) switch, meaning that it has a single common terminal and a single set of contacts that can either be open or closed. It is a toggle switch meaning the user can turn it on and off by pressing the rocker switch. The switch is housed in a small body size of 22.8 x 17.2mm, allowing it to be used in places where space is limited. The maximum voltage rating of this switch is 25V AC/DC and the maximum current rating is 20A/240VA. The contact resistance is also quite low, at 12mΩ max. This rocker switch is also suitable for use in damp and washdown environments.

Installation

This rocker switch can be installed on a variety of different surfaces. It can be mounted onto panels using a choice of brackets or clips, or alternatively it can be mounted onto a circuit board. The switch is also easy to install, as the contacts and terminals are easily accessible and very durable. The terminal is also easy to connect to other circuit components such as resistors, transistors or integrated circuits.

Application Fields

The JWM21BA2A-B Rocker Switch has a myriad of applications. It is ideal for use in a large range of small-scale applications including home appliances, consumer electronics, electric tools, industrial machinery, test equipment, and instrumentation. It is often used as a control switch or power switch in various types of electronics, computers, appliances, and lighting.

Working Principle

The basic working principle of this rocker switch is quite simple. When the switch is in the on position, the common terminal is connected to the other set of contacts and current is able to flow through this connection. When the switch is in the off position, the common terminal is disconnected from the other set of contacts, and no current is able to flow through. This switch also features a set of contacts that are resistant to arc flash and can operate for long periods of time without any degradation.

Conclusion

The JWM21BA2A-B Rocker Switch is a great example of a small-scale rocker switch. It is a SPST (single pole, single throw) switch and is suitable for a large number of applications. This switch has a low contact resistance and is also suitable for use in damp and washdown environments. This switch can also be used as a power switch in a variety of different applications, including home appliances, consumer electronics, electric tools, industrial machinery, test equipment, and instrumentation.
