Automobile Rocker Switch: How Does it Work on Your Auto Wiring Harness

Do you know how your vehicle’s windows move up and down? It’s because of the automobile rocker switch harness, which connects with motors to allow the movement of window panes. 

This article will teach us how the rocker switch wiring harness works on automobile electric systems.

Automobile rocker switch understanding:

An automobile rocker is an electrical switch that moves front and back on a pivot point on pressing. When you press the switch, the switch gets raised from one side and pressed from the other like a garden seesaw. 

These rocker switches need low amperage circuits and thus are suitable for vehicle dashboards and other electronics.

Some electronic systems are power door locks, heated seat switches, power window movement, and rear window defogger grids. 

All modern vehicles come with rocker switches to operate electronic functions efficiently. You can find them in their basic form or the spring-loaded form.

Some rockers come with a spring-loaded switch that helps the switch return to its original position after release.

You must have used such a switch on the power door lock. When you press this switch, the switch moves to one side to allow locking and unlocking of the door.

However, it comes to its original position when you release the button. Similarly, a power window switch pivots back and forth for window movement but comes to its central position on release.

A spring-loaded rocker switch returns to its center position through its spring-loaded mechanism. You need not deactivate the button for that. 

Some rocker switches have a timer that gets activated when pressing the button. Even after releasing the button, the feature functions until the timer completes. You can find them in the grid button of the rear window defogger.

Wiring Diagram For Electric Window/Powered Door/Heated Seat/Rear Window Defogger Switch (Polarity Reversing 5 Wire Rocker Switch) 

It simply explains how a 5-pin rocker switch works on an Electric Window/Powered Door/Heated Seat/Rear Window Defogger system.

Experts recommend adding an in-line fuse to the connection from the battery to the switch, and also, don’t forget to use a relay in high-current applications.

The switch’s working depends on the polarity of PINs 1 and 5, whose reverses are based on the direction of the switch movement.

When the switch remains at its original position, PIN 1 connects to PIN 2 and PIN 4 to PIN 5. As a result, the output towards the motor, i.e., PIN 1 and 5, remains on the ground. As a result,  the motor does not work. 

However, when you press the switch towards the left, PIN 1 disconnects from PIN 2 and connects to PIN 3, which sets the first motor connection +ve.

However,  the second connection, i.e., PIN 4 and 5, remains on the ground or at zero voltage, and the second motor doesn’t work. As a result, the motor moves in one direction. 

The opposite process starts if you press the switch towards the right. Here, PIN 5 disconnects with PIN 4 and sets the connection with PIN 3.

PIN 1 connects to PIN 2 and remains at the ground voltage. As a result, the second motor connection activates while the first doesn’t work. So,  the motor runs in the opposite direction.
