Description

The invention relates to electrical engineering, in particular to packet switches.

The purpose of the invention is to reduce the size and increase the number of switching positions.

Figure 1 shows the switching package, front view (along the axis of the shaft); Fig, 2 - section aa in figure 1,

A batch switch contains a set of switching packets. Each package includes a housing 1, flexible elastic contact lamellae 2, mounted on brackets 3, a rigid contact plate 4 located across the contact lamellae 2, a pusher in the form of a plate 5 with lugs 6 and a cam 7 having lugs 8. The number of lugs 8 can be different depending on the set switching programs. The pusher 5 is placed between the slats 2 and the cam 7 across the slats 2. The cam 7 in the package is placed in bulk 9, on which all switching packages are fastened, fastened together by studs 10.

The switch works as follows.

When switched on, the cam 7 rotates together with the shaft 9, the cam protrusion 8 does not interact with the protrusion protrusion 6, and the contact lamellae are closed with a rigid contact plate.

When turned off, the protrusion 8 of the cam 7 acts on the protrusion 8 of the pusher 5, which simultaneously pushes the contact lamella 2 from the contact plate 4.

When the pusher 5 is located closer to the place of attachment of the lamellae 2, it is possible to increase the contact solution without increasing the dimensions of the switches intended for use in auxiliary chains of constant

for example contactors. If, however, the pusher is moved to the farthest distance from the point of attachment of the lamellae 2, then a minimum contact solution can be obtained for switches operating in AC circuits.

In the proposed switch, the number of switching positions is increased without duplicating them, since it is possible to rotate the shaft with a cam within 360 due to the fact that one cam lobe acts on the two lamellas. An increase in the number of switching positions in each packet reduces their number, and consequently, the overall dimensions of the switch.
