Dividing webs which are also made of the casting compoundmay extend between the terminal elements in the terminal compartment. Tomanufacture the primary part, a die having a complementary shape to theterminal compartment to be formed is introduced into a housing beforecasting and the terminal elements are attached to the die before casting.After casting and curing of the casting compound, the die is removed.
