Rocker switches – most likely ET21J6CBE2 – are commonly used in many everyday applications, such as switching lights and appliances on and off, controlling motors, and regulating temperature. They are also used as power control switches in vehicles, aircraft, and boats.

A rocker switch is an on-off switch, typically rectangular in shape, with a lever that can be pushed up or down. This lever activates two internal contacts, which allow power to be connected or disconnected to a device. Each of these rocker switch models has its own distinctive features, making them suitable for a variety of applications.

The ET21J6CBE2 is a Single Pole Single Throw (SPST) normally off rocker switch, making it ideal for applications where a circuit needs to be broken when the lever is pressed down. It is usually used as a momentary switch – a switch that is only active while the lever is pressed. ET21J6CBE2 is a relatively large switch with a robust build, making it suitable for use in heavier duty applications such as agricultural and construction machines. It has a heavy-duty insulation panel which makes it an excellent choice for high-vibration environments.

In terms of electrical specifications, the ET21J6CBE2 has a rated voltage of 125V AC/1.5A and 24V DC/3A. It has a contact resistance of less than 50 mΩ and an insulation resistance of greater than 100 MΩ. It also has an electrical life of 10,000 cycles. Additionally, the ET21J6CBE2 is rated for temperatures between -20 to 70°C and carries an IP67 rating, indicating it has been tested for protection against liquids and dust ingress. It is UL, cUL, and TUV approved.

The working principle of a rocker switch is relatively straightforward. When the lever is pressed, one of the two internal contacts is activated, and power is supplied to the connected device. When the lever is released, the other contact is connected and power is cut off. This process is repeated each time the lever is pressed and released.

The ET21J6CBE2 rocker switch has a wide range of application fields, making it ideal for use in a wide variety of different environments. It is commonly used in the automotive and aviation industries for controlling fuel and power systems, as well as in industrial and agricultural machines for controlling motors and other components. It is also commonly used in household appliances and electronic devices, such as TVs, DVD players and air conditioners, to switch them on and off.

In conclusion, the ET21J6CBE2 is a robust and reliable rocker switch, making it suitable for use in a variety of applications. Its rated voltage and electrical life specifications, combined with its heavy-duty insulation panel, make it suitable for use in high-temperature and vibration environments. Its working principle is straightforward, allowing for easy integration into any existing system.
