Rocker Switches: ET21J1V3BE2 Application Field and Working PrincipleRocker switches are commonly used as electrical switches, which are especially suitable for applications that require an independent on/off switch. The rocker switch is activated by pressing the upper or lower part of the switch, which causes the switch to oscillate slightly, thus completing or interrupting the electrical connection. ET21J1V3BE2 is a type of rocker switch. This article will discuss the application field and working principle of ET21J1V3BE2.ET21J1V3BE2 is a double pole double throw (DPDT), non-illuminated, push-on rocker switch. This switch is used to control the push-release of two circuits. The switch structure consists of two movable contacts that rotate to the two stable positions. When the switch is manually pressed, the movable contacts will rotate to the two stable positions, thus completing or interrupting the electrical connection. The application field of the ET21J1V3BE2 rocker switch includes automotive, industrial, appliance and heavy commercial/military applications. The switch is also widely used in low power circuits, such as for controlling motors and lights. Additionally, the ET21J1V3BE2 rocker switch is widely used where precise switching is not required, but a long life span is desired. In particular, due to its robust structure and insulation material, the switch provides superior resistance to high levels of mechanical vibration and electrical shock.In terms of its working principle, as mentioned before, the rocker switch\'s movable contacts rotate to the two stable positions when the switch is manually pressed. The rotation of the movable contacts is enabled by a plastic rocker arm, which is linked to the switch body and the movable contacts. The plastic rocker arm is secured in place by two metal pins, which provide the required friction to hold the contact position. Once the contacts are rotated to the two stable positions, they remain in position until the switch is pressed again. In summary, ET21J1V3BE2 is a double pole double throw (DPDT), non-illuminated, push-on rocker switch, which is widely used in automotive, industrial, appliance and heavy commercial/military applications. The switch operates by the rotation of two movable contacts, which is enabled by a plastic rocker arm, thus completing or interrupting the electrical connection.
