BZ-R21-A2

A snap action switch, otherwise known as a limit switch, is a device that provides an electrical interruption system when the actuating arm of the switch reaches a certain position (or point). The BZ-R21-A2 is a type of snap action switch known as a metal snap switch. It has a single pole, a single throw, and a normally open contact.

The BZ-R21-A2 metal snap switch is a versatile, reliable limit switch that can be used for a variety of different applications. It is designed for use with alarm systems, security systems, vending machines, money-counting machines, and other similar systems that require an electrical interruption when the actuating arm of the switch reaches a certain point. It is a highly reliable switch, and is approved by several safety agencies, including UL and CSA.

BZ-R21-A2 Application Field

The BZ-R21-A2 metal snap switch is ideal for applications that require an electrical interruption system when the actuating arm of the switch reaches a certain point. Examples of such applications include alarm systems, security systems, vending machines, money-counting machines, and other similar systems. In addition, it is also suitable for other applications that involve controlling the mechanical motion of a device.

The BZ-R21-A2 metal snap switch is designed for use in environments where high levels of vibration and shock resistance are required. It is also designed for reliable operation in hostile environments, such as extreme temperatures, wet areas, and corrosive atmospheres. Additionally, it has a long working life and is highly reliable.

BZ-R21-A2 Working Principle

The BZ-R21-A2 metal snap switch is designed to detect when the actuating arm of the switch reaches a certain point, and then to provide an electrical interruption. The actuating arm is connected to a switch lever, which is connected to the electrical contacts. When the actuating arm reaches the predetermined point, the lever moves, and is then able to make contact with the electrical contacts. When the contacts meet, the switch closes and electricity can flow.

The BZ-R21-A2 metal snap switch is designed to be highly reliable and provide an electrical interruption when it is needed. In addition, it is designed to be easy to install and operate. Once installed, the metal snap switch is easy to maintain, and replacement parts are readily available. The metal snap switch is also UL and CSA approved, meaning it is safe to use in most applications.

Conclusion

The BZ-R21-A2 metal snap switch is a reliable and versatile limit switch that can be used for a variety of applications that require an electrical interruption when the actuating arm of the switch reaches a certain point. It is designed for use in hostile environments, and is highly reliable and easy to install and maintain. Additionally, it is UL and CSA approved, making it extremely safe to use in a variety of applications.
