Description

The proposed switch for parts of radio devices, batteries, electric lamps, etc., has the purpose of disconnecting unnecessary parts of a radio device or other device (for example, self-induction coils, resistances, capacitors, etc.), for which purpose the switch it is equipped with two disks having relative to each other movement and equipped with a certain number and a certain form for the length of each contact disk. The switchable parts are connected to contacts fixed on the panel and capable of contacting the contacts of one of the disks.

In FIG. 1 shows a section through a switch; FIG. 2,3,4,5,6, its separate parts.

The switch for parts of radio devices, batteries, electric lamps, etc., consists of two DI and Dg disks made of an insulating material. The DI disk is fixed pivotally on the axis O, and the disk D is fastened with it motionless. The axis O is passed through the panel P, against which the disks DI and Da are pressed by the coil spring R, which is mounted on the axis O and the adjustable nut G (Fig. 1). The disk D is provided with an even number (2p) of the contacts KI, HI, Cs) On, passing through the disk and placed along it at equal distances along the arc from each other (Fig. 3) and also has a contact that does not through the disk, and connected with a metal ring M fixed on the rim of the DI disk, along which the spring Q slides. The stationary is fixed on the panel P (Fig. 1 and 3).

The KI, HI contacts of the DI disk can come into contact with the circular contacts K, H .... by the number 2p with which the panel P is connected to the switchable parts (Fig. 2). Thus, the DI disk on the side of the inner side facing the panel has 2p contact lamellae, which can come into contact with the 2p contacts of К.1, HI, К ,, On -... panel, and on the side of the outer side facing the inner side of the disk D, has 2 HI 1 pin 1.2 ... 2n-1 (Fig. 4). On the side of the disk Da facing D, there are n-1 shaped contacts C, C and a slider P connected electrically with axis O. Contacts GI, Cj ... are of such dimensions that they can overlap two adjacent contacts 1, 2 ... on the outer side of the disk D, and the slider P can block only one of the contacts 1, 2 of the disk DI (FIG. 5) or, as shown in FIG. 6, contacts C, can block more than two contacts 1,2, and the slider P more than one contact 1,2, of the same DI disk.

The current is applied to the contacts, and therefore to the switchable parts, batteries, electric lamps, etc., through clamp A connected to spring Q, making sliding contact with ring M and through clamp B along the axis O. Switching parts, batteries, electric lamps, etc., is done by moving the disks D and Od relative to each other and moving the slider P until the contacts on the named disks are aligned.

. The subject matter of the invention.

A switch for parts of radio engineering devices, batteries, electric lamps, etc., characterized by the use of two DI and D discs (Fig. 1) made of an insulating material, one D of which is pivotally fixed on the axis O, passing through the panel P, and the other Dj is fastened to this axis O, which disks are pressed against the panel by the spring R mounted on the axis O and are equipped with: a) the disk Dj with an even number (2p) of the contacts Ki, HI, Kag Hj., .. (Fig. 3), passing through the disk, and one contact N, not passing through the disk and connected to the ring M (Fig. 1 and 3), reinforced on the rim of the disk, on which the spring Q slides, mounted on a panel equipped with the same number (2 n) of contacts K, H ... (Fig. 2) connected to switchable parts that are in contact with the contacts of KI N. disk b) the disk D is equipped with (p-1) shaped d, Cj contacts (Fig. 5) or C (Fig. 6), which can overlap each two or more contacts 1, 2 of the D disk and are connected to the axis O and the slider P (Fig 5, 6), which can overlap one or more contacts 1, 2 of disk 1, whereby the current is supplied to the switch along the axis O and the terminal a connected to the spring a.
