The vjd2 rocker switch has 10 posts on the back and is a variation on our dependent lamp on off on rocker switch body or vjd1. A rocker switch is a switch which consists of a piece which rocks back and forth in response to pressure to open and close a circuit.

How does rocker switch work. A double pole double throw switch is used for this purpose but you have to wire it up correctly. The rocker switch then can play a role as an on off switch in the circuit so that it can turn on or turn off different devices in a circuit or the entire circuit itself. When they do the switch may work when the toggle is up or down but not in both positions. This can make you think two wires are in each others place but the switch simply needs to be replaced. The photo shows a dimmer switch that can be used as a single pole switch or as a three way switch. This circuit uses a tremendous amount of current.
Rocker switches are commonly used as light switches and they can be used in a variety of other applications as well. Although all of these switches operate a little differently from each other they share common switch configurations that determine how they operate and what kind of devices they are suited to switch. Rocker switches are common components in many different types of electronic circuits that allow power to be turned on or off. Wire a dpdt rocker switch for reversing polarity. These switches fail in time due to overheating. There are rocker switches toggle switches slide switches button switches rotary switches pull switches and more.
When the ignition switch is open a small amount of current is delivered to the starter solenoid which then opens the circuit that operates the starter motor. Many appliances and surge protectors for example are fitted with rocker switches. You would most often use the vjd2 instead of the vjd1 when this switch will be triggering two loads but not the backlights in a bank of backlit rocker switches. The starter solenoid is essentially a large relay itself. When you need to control a dc motor such as a dc linear actuator you usually need to be able to swap the polarity on the wires going to the motor.
