Reference numerals 17 and 18 denote through holes penetrating through the main body 9a and the lid 9b, which are connected to one another with the aid of pins 19 to form the contact housing unit 9. For attaching the contact housing unit 9 to the electromagnet housing 1, the former is pushed in the longitudinal direction of the gripping pieces Id and the gripping pieces 5b, the Gripping pieces ld, Id attached to the top of the top box Ib protrude into the in the bottom surface of the Kbntakfcgihäases 9 formed re-entrant grooves 9c, 9c inserted and the gripping pieces 5b of the connecting element 5 in the re-entrant Grooves 9e are used so that the gripping ends 5c, 5c engage in the slots lob, lob, which in the lower end portion of the support member Io are formed. Since at this point the lower ends of the Stopper 15 are in contact with the housing, the contact housing unit is pressed by the springs 16 upwards. If the stoppers 15 get over the recesses Ie of the housing 1, the lower ends of the stoppers fall below the action of the springs 16 in the recesses Ie, so that the displacement of the contact housing 9 is stopped. Consequently the contact housing 9 rests on the housing 1 and is connected to it. This mutual connection between Contact housing 9 and the housing 1 is shown in the figure. By combining three such contact housings

S to the housing 1, it is possible to form a three-pole magnetic 'control apparatus according to Fig.2. To simplify the displacement of the contact housing 9 on the housing 1, the stoppers 15 are rounded in the direction of movement, as can be seen from FIG. Thus, the contact housing 9 can be displaced against the action of the spring 16 without difficulty, with only a small force being applied; the contact housing 9 can thus be attached to or detached from the housing 1 without difficulty. Fig. 3 shows a contact housing for normally open contacts in the attached state. However, it is also possible that a contact housing for normally closed contacts, as shown in FIG. 7, can be put on instead of one with normally open contacts.

Fig. 8 shows a magnetic double contact control relay in which the contacts are arranged in two stages with one of the two contacts normally open and the other normally closed.

Fig. 9 shows a magnetic triple-action BUBireläis in which the contacts are arranged in three stages, with two of the three contacts normally open and the other normally open normally closed. If the intermediate contact is normally closed, it is possible to use a magnetic one

009813 / U90

To obtain control relays of the triple contact type, with one of the contacts normally open and the remaining two contacts normally closed are.

From the above it follows that according to the invention on the housing 1 not only a single contact but also a double-contact or triple-contact contact housing can be attached without difficulty, as is is shown in Figs. The advantage of the invention is therefore that it is possible to make any desired To meet contact arrangement.

In the magnetic control relay according to the invention, an electromagnet M is used which has a sufficient capacity to actuate three contact housings of the triple contact type attached to the housing 1 as shown in FIG. Therefore, there is a risk that the fixed core of the electromagnet M is violently struck by the movable core 4 in the event that contact housings of the double or single contact type shown in FIGS. 7 or 8 are used. To eliminate this risk, a buffer spring 2o is provided. This spring will now be described. According to his invention , a normally

closed contact can only be achieved by supporting the movable contact 11 with the aid of a spring 12 which is arranged in a window opening loc formed in the support element Io under the window opening loa, so that the fixed contacts .13 »I ¹ J and the movable contact 11 can be used for both the normally open type and the normally closed type (see Fig. 7). Thus, in the case of the normally closed type wherein it is supported by a spring 21 in such a _$ is the buffer spring in a window opening loa for normally closed contact set, that the opposite ends of the spring 2o loa protrude from the window opening and engage in recesses 9f are formed on the opposite side portions of the contact housing, between which the support element Io is inserted.

In the case of the normally closed contact type, the fixed contacts 13 and 14 are bridged by the movable contact 11 before the movable core 4 abuts the fixed core 2 violently. In this case, the support spring 12 serves as a buffer, so that no further special buffer spring is necessary.

The reference numerals 22 and 23 denote through

holes that extend through the contact housing 9. These through holes are provided for receiving screws 24, with these with the help of nuts or Like. To attach the contact housing to the housing 1.

Fig. Io shows a fixed to the housing 1 contact housing 25 for large capacity. In this case it is made the execution so that on the housing area of the housing 1, on which normally three contact housings sit, only two contact housings are arranged, as shown in FIG. In this way a double pole magnetic control relay is created.

According to the invention is also the cover 9b, which is on each Contact housing is attached, marked with different color to tell the difference between the normally to clarify open contacts and normally closed contacts. Thus the inner Contact arrangement can be determined from the coloring without difficulty, since the side end face of the cover 9b, each contact housing 9 faces outwards even in the case in which the contact housing placed on the housing 1 9 correspond to three poles, as shown in Fig. 2 *

while in the case of the double contact type the Construction is such that one of the contacts is normally open and the other is normally closed, so are those upper and lower portions of the lid 9d accordingly the contact arrangement in different colors, as shown in Fig. 12a. In Figures 12b and 12c show covers for the triple contact housing, which are identified in different colors are to make a difference between the arrangement where two of the contacts are normally open and the other normally closed and the arrangement in which one of the contacts is normally open and the other two contacts are normally closed to illustrate.
