Description

The invention relates to devices for the operation of and individual selection of object management in systems for selective control of production processes.

Known multi-switch key switches, in which, for the purpose of reliably releasing the buttons of one row when the ml ml KHo ;; iOK of the other row is turned on, each row of buttons is equipped with an additional ruler, ensuring their removal with a predetermined power reserve.

The disadvantage of the first switches is the complexity and cumbersome design of the ycTpofiCTB inter-link communication, which is especially evident in the application for the two-row switch.

In the preceding two-way cell, the switch of the switch row at the ends is connected) by inter-link communication mechanism (.1 two ways: for decadal selection of control objects. By pressing any number of units, the previously pressed and fixed key is turned off only yes units, and when you press any key, the number of tens keys turns off the previously pressed and locked keys of a number of tens and a number of units, while simultaneously switching on two keys in a number of units or in a row of tens is excluded.

The intercommunication mechanism is located in a bracket that is mounted; between the direction of the young plastic: the 1st row of the .tüch. body and fastened with them with pints. Kpoinureiiii has an axle with a spring loaded on it

In the case of individual selection of control objects, between the right-hand plates of the switch rows are installed: two brackets, with one bracket mounted, having an axis with a spring-loaded rocker mounted on it, the ends of which enter the holes of the separate rows of switch rows, and On the left side - KpOHHJTefi, which has an axis with 1 adorned lateral rocker, the ends of the Kovo / ni-ii enter into the slots of the edge blocking support plates of individual rows of nonferrous.

A cool switch row contains working buttons 7 (see Figs. 2 and 3) with a rod 8. installed with pins 9 and booster springs W in the holes of the nrl .1; n (nlx nlastin // which are connected to m (. 1) racks 12 and w / 5.

Between plates 11 and coitag, tangible groups J8 on the rods 8 are placed shock-absorbing rings 22. To the base 2 of the switch body 1 by means of gtosk 24 and V.INT 25, a board 26 with sliding contacts 27 is attached. Rows of switching the bodies are interconnected with po-hiii of brackets 28 and 29 (see fig. 4) to which pi lt; 1 25 and 25 connections1 :; e | 1y with the base of 23 Cornus with the help of racks ./. In the bracket 28, the axle 32 is reinforced with the yoke 33 put on by its ira, and sub-axle 1P1 / HNT of the torsion spring 34 (see Fig. 2). The ends of the rocker arm 33 are inserted into the slot of the fiesptor 14 p yes of units 5 n into the hole of the fi lter 14 p of 10 six (sms fng. 4 and fi). In the bracket 29, the axis 32 is fixed with the yoke on it, which is equipped with an arm 35, the end of which is inserted into the slot of the retainer 14 and the units, M1, 1 and 55, is pressed by the torsion spring 36 (see Fig. 2, 5).

To remove the keyboard switch from the console panel and install it into the folders, knobs 37 are used (see Fig. 7), which are screwed into threaded bushings 38 (see Fig. 8), which are inserted into L1 of the switch panel 39 of the switch case using

special nuts 40. There are 1 - 1 sleeves 41 in the openings of the sleeves 38 110, which prevent the thread of the holes from the dusting of the holes, which are mounted using springs 42.

When pressing the key 7 of any row, the rod 8 with the pin 9 moves in the holes of the plates 11, and the pin 9 slides along the beveled surface of the latch M. A locking mechanism consisting of floating plates 15 provides a gap equal to the diameter of the pin 9. When moving The rod 8 pin 9 pushes the locking plates 15 into the row of the pressed key and, by selecting a gap, prevents the simultaneous 1inclusion of more than one key in the row. Upon further movement of the rod 8, the contacts 20 of the contact group 18 are closed with the stationary contacts 27, and the pin 9 of the rod 8 is fixed, dropping into the slot of the latch 14.

When you press any other key in the row of units 5, the process is repeated, and the previously turned on and fixed key of this row returns to its initial position at the moment of moving the latch 14

This is due to the spring 10 action. In this case, the movement of the lock 14 rows of units due to the free movement of the lock slot relative to the end of the rocker arm 35 is not transmitted to the lock 14 rows of tens. The latch 14 rows of units returns to its original position when using the rocker arm 35 and the spring 36. | When you press any other key in the row of dozens, the previously included keys of both rows return to their original position at the moment you move the lock 14

In order to make the selection of control objects according to the individual election system, the key switch has two rows of keys 7 with sequential numbering. In this case, the rows of the switch are connected. The interoperable p / v of the help of the brackets 25 and 29 (see fng. 6) is similar to the switch for the decade electing system. In the bracket 28, the axis 32 is fixed with the one put on it

rocker 33, spring loaded torsion spring 34. The ends of the rocker arm 33 are included in the holes of the clamps 14 of both rows.

In the bracket 29, the axis 52 is reinforced with a yoke mounted on it1slom 43, the ends of which
