Abstract
A miniature relay switches a very large current without causing a deterioration of nearby insulation. This is done by providing relatively large clearance spaces in the areas where particles eroding from the contacts might be deposited. Also, housing walls separate the contacts from these areas of particle deposition. Without this clearance space or walls, the deposited particles might cause a short circuit. The invention also provides many structural details which enables the miniature construction.
