Abstract
A contactor includes an upper housing (1) for contact parts and a lower bobbin (5) that bears a coil and can be placed therein in an initial position or in a position displaced by 180 degrees. The coil terminals (6, 7) lie next to each other on one side of the bobbin (5). Before the assembly of the bobbin (5) in the housing (1, 4), at least two male parts (2, 3) comprising terminal pins, and at least one female part (8, 9) comprising a hole that is intended to receive one of the male parts (2 or 3), are molded on at the areas that will subsequently border each other. In order to arrange the coil terminals (6, 7) on one side of the contactor, the male part (2 or 3) that does not act in conjunction with a female part (8, 9) in this position must be broken off prior to assembly. In order to arrange the coil terminals (6, 7) on the other side of the contactor that is turned away by 180 degrees, the other male part (2 or 3) must be broken off. Advantageously, in this arrangement the coil terminals always lie unmistakably at the predetermined, accessible side of the uniformly manufactured contactor.
