Mains polarity changeover switch allows you to swap the polarity (positive and neutral) on the incoming mains supply.  Ideal for use on continental camp sites where the hook up can be wired either way without warning!

Checks the polarity on continental sites.  The mains polarity changeover switch is installed between mains inlet socket and mains distribution/transformer unit.  When plugging into a continental hook up, if red light shows - simply change switch to swap polarity and make the supply safe to use with your appliances. Saves any guess work, leaving things to chance or use of adapter leads.

We suggest this product is installed by a competent person.
