Expansion Box
he new improved switched Expansion Box allows you to move seamlessly through the brush plating process without having to switch the connections round at the rectifier.
A switch replaces the requirement to reverse the leads when performing operations such as chrome stripping. Another feature of the new expansion box is a flashing red light which warns you when you are in stripping mode.  This helps prevent one of the most common problems in brush plating; going into the activation stage with the electrical current flowing in the wrong direction which can cause damage to the work.
It also alleviates the requirement to stack the connections at the rectifier which not only looks more tidy, but helps prevent electrical problems.
