Reverse polarity protection

What is reverse polarity protection?

It can sometimes happen that electronic devices are connected the wrong way round. Reverse polarity protection ensures that devices are safe when connected incorrectly. It protects the electronics from breaking. When the battery terminals are connected incorrectly, reverse polarity protection will prevent the voltage from passing through. For example, when the plus is connected to the minus and the minus is connected to the plus. Not letting the signal through results in no damage to the connected device. When the poles are connected properly, the protection will obviously do nothing. Then the device or lighting will just work as it normally would. So it does not affect the operation of the devices when connected properly. It purely provides a piece of protection for the electronic device.

Safety in LED lighting

Reverse polarity protection can also be useful when connecting lighting. Naturally, you don’t want your lighting to break because it’s been connected the wrong way round. There are lights where it doesn’t matter whether you connect the positive and negative terminals correctly. These lights are not polarity-sensitive. Examples include licence plate lights and marker lights. With LED lighting, things are slightly different. This is because LEDs are oriented in one direction and therefore only work in one direction. This lighting is, in fact, inherently polarised. The signal is never transmitted in the opposite direction. The light therefore cannot simply break if it is connected the wrong way round.
