Description

Switches are widely known in electrical engineering for automatically turning on and off several receivers of electrical energy at a predetermined time. Similar switches are known, in which a number of contact bars are used, electrically connected to current receivers, and a contact slider, driven by a clock mechanism and sliding along fixed contacts.

The proposed device relates to such switches and consists in a special constructive form of implementation of the switching mechanism.

In FIG. 1 and 1 depict a schematic view of the device in two projections and FIG. 2-schematic connection with the drive mechanism, namely, with the clock.,

The device consists of a switch equipped with a contact slider / 2, consisting of two parts 16 and 17, isolated from one another by a gasket 15. The slider / 2 moves along two rows of contacts 10, 10 ..., 9 ... and along the contact tires 13 and 14nofi, the action of the clock mechanism. Contacts 9.9 .., 10, 10 ... are connected to tires 8, S ... equipped with contacts 7, 7 ... Above tires 8, 8 .... are perpendicular. (231)

Tires 4, 4 .. connected to them with plug contacts 1, 1 - .. serving to turn on the receivers; In addition, buses 4.4 .... are connected to lever switches 6, 6 ... by means of which they can be connected to contacts 7, 7 ... Tires J3 and J4 can be switched using a terminal switch 2 /, driven B action contact slider / 2. For the drive of the slider 72, a cord 28 is used (Fig. 2), thrown over block 26 and connected to the weight of the 25 clock mechanism 27. The current source is electrically connected to terminals A and D If the receivers are included in the plug contacts /, 7 ..., This current, coming from terminal A through receivers, buses 4 and lever switches 6, 6 .., is directed along horizontal tires 8, 8 ... to contacts I and I then through sliding contact 18 of slider 12 to contact bus 13 and through terminal switch 21 and wire 3 to terminal B; in this case, when moving the sliding contact 18 of the slide / 2 from one contact plate 9 to the adjacent one, the electrical circuit is not interrupted, since the sliding contact simultaneously touches both plates. If any lever switch 6 is not connected to the corresponding contact 7, then between contact 9 and vertical bus 4 the electrical circuit will be open for as long as the sliding contact / moves along the contact 9.

When the slider reaches the extreme lower plates / and fO, the stop 22 of the slider 72 will retract the pawl 23, the spring 24 will not switch 2 / s from the contact LZ for the 73 tire HSf and 74 M at the tire. plates, located in FIG. 1 on the right, via vertical bus J4. Since the slider 72 is connected to the weight of the 25 clock mechanism 27 (Fig. 2), while the weight 25 is above the block 26, the slider will go down under the influence of its own weight at the lowest position; when the weight 25 falls below block 26, it protrudes slider 12 with its weight and forces the latter to move in the opposite direction, i.e. upwards.

The subject matter of the invention.

Claims (2)

1. A device for automatically switching on and off receivers of electrical energy at a predetermined time, using a series of contact tires electrically connected to switch receivers to turn on receivers in one or another combination and a contact slide driven by a clock mechanism and sliding on fixed contacts, such as, the contact slider 72 consists of two contact parts 16 and 77, each of which, for a number of fixed contacts, respectively I 9 .... and 10, 70 ..., and according to their respective guiding contact tires, respectively 73h 74, switched by means of a terminal switch 2 / driven by a slider 12 so that the tire, for example 74, turned off from the circuit when the slide 12 is turned down, is turned on before the move of the slide / 2 up, while simultaneously turning off 73 other tires. 2. The form of the device according to claim 1, characterized in that the rotating unit 26, through which the cord connecting the slider 12 with the weight, 25 clock mechanism, is located between the end positions of the weight 25 so that when lowering the weights 25 —the crawler 72 was first lowered by its own weight, and then lifted under the action of the weight of the weights 25.
