E301J3V21QE2

Rocker switches are flexible and versatile components that are used as part of many electrical circuits. The particular rocker switch being discussed here is the E301J3V21QE2 designed by Electroswitch. This particular switch is a high current, instant-on switch and it is commonly used in industrial and military applications.

Mechanical Construction

The switch consists of two metal contacts and a rocker mounted on a plastic base. The metal contacts are arranged in a curved shape and the switch is mounted on a plastic base measuring 3.44” x 1.14”. When the rocker is moved, the two contacts make and break the electrical connection, allowing the switch to be either open or closed.

Types of Operation

The E301J3V21QE2 rocker switch has two types of operations: latching and momentary. In latching operation, the switch remains in either the open or closed position until it is manually reset.In momentary operation, the switch is open when the rocker is in the neutral position and closed when the rocker is moved in either direction. This momentary operation is suitable for applications such as pumping water, controlling fans and motors and other applications where power needs to be quickly switched on and off.

Protection

The E301J3V21QE2 rocker switch is designed to provide reliable and robust performance in harsh environments. The contacts are designed to resist arcing, corrosion and welding. The switch is UL listed and can handle up to 25 Amps of continuous current.

Mounting

The E301J3V21QE2 is designed for panel mounting. It has two mounting holes, located in the center of the base. The switch can be mounted directly to the panel or it can be mounted to a metal plate and then attached to the panel.

Summary

The E301J3V21QE2 rocker switch is a high-current, instant-on switch with two types of operations: latching and momentary. It is designed for panel mounting and is suitable for industrial and military applications. The switch is designed to provide reliable and robust performance, and it is UL listed for up to 25 Amps continuous current.
