United series and changeover connection.

Patented in the German Empire on December 30, 1924.

There are known alternating series connections,

which enable two lamps or rows of lamps to be switched on and off from two locations turn off. However, there is usually a restriction with regard to the sequence the connection and disconnection at the two switching points.

The present invention enables the second row of lamps to be used from each switch to be switched on from the first row of lamps.

To achieve this, two different switches are connected to one another. One switch is a series switch, the shift drum covering of which has a slip ring communicates with a fifth terminal and the other is switch a double switch with two switching drums, whose contact assignments each have a slip ring with a fifth and a sixth ίο Terminal are connected.

The simple switch (Fig. I) has a porcelain base α, which in principle corresponds to the porcelain base of the switches previously used. Four contact springs b ¹ to b * are attached to this base at a distance of 90 °. On the porcelain base there is also a sliding contact c ¹ , which is attached between two contact springs so that it is 45 ° away from them. It establishes the connection with a slip ring d ¹ located on the lower face of the shift drum. Contact assignments are bent upwards from this slip ring at two points that are at an angle of 90 ° to each other. The turns are on the perimeter of the! Roll up. The toggle and the other components of the switch are the same as those of the switches previously used. I.

The double switch (Fig. 2) has two switching drums lying one above the other, which are isolated from each other by a ring-shaped porcelain attachment. On the porcelain attachment there are two sliding contacts c ¹ and c ² , which lead to slip rings on the upper side of the upper shift drum and the underside of the lower shift drum. As in the case of the simple switch, contact assignments are bent from these slip rings, which are exactly one above the other for both switching drums. Of the four slip springs, springs b ¹ and b ^{3 are} in contact with the lower shift drum and springs b ² and & * are in contact with the upper shift drum. The two switches are connected to one another, to the power source and the lamps, as shown in Fig. 3. In the switch position shown, both lighting series are on. The current path is then as follows: The current goes through the lead I to the switch 1, to the sliding contact c ¹ , and through the sliding bridge d ¹ to the contact springs b ¹ and b ² . From the contact spring b ¹ the current continues through the line e to the switch 2 to the contact spring b ^{2 of} the switch ² , through the sliding bridge d 2, through the sliding contact c ~, the line / to the lamp 2 and to the return line II. From the contact spring b ² of switch 1, the current continues through line / to contact spring b ¹ of switch 2, through sliding bridge d ¹ to sliding contact c ¹ , further through line k to lamp 1 and then to derivation II. When switch 2 is rotated 90 ° is then the lamp goes out i and lamp series II continues to burn because the leading to the lamp 1 wiper fr deenergises ¹ and leading to the lamp 2 wiper "b further current remains. When 2 of the switch 1 in the last-described position of the switch is turned 90 °, then no more lamp series burns. The contact springs b ² and b ^s are then occupied with switch 1. These are connected by lines f, g to the contact springs b ¹ and & ⁴ of switch 2. Since these do not have any Have contact with the slip rings d ¹ and d ² , the line to both lamps is interrupted. In addition to the circuit examples mentioned above, there is a whole range of circuit options. You can switch both lamp series on and off one after the other using switch 1; the same can be done from switch 2. You can switch on a series from switch 1, the second series from switch 2, switch one off again from switch 1 and then switch off the other from switch 2; you can start switching at switch 1 or 2 and continue the other switching operations at each of the two switches, without being tied to a specific order in which the switches are used.

Claims (2)

Patent-A N proverbs: 1. United series and changeover circuit, characterized by the connection a series switch, the shift drum cover of which is connected to a connection contact by a slip ring, with a switch with two superimposed switching drums, both of which have contact assignments are each connected to a terminal by a slip ring. 2.
