subject to "Queteoh capacitor".

For Abglelohsweoke In the Sadloteohnlk so-called _A Quetsohcondensers are known, which consist of a combination of both a fixed capacity which is as insensitive as possible to pressure and a capacity which can be changed by means of pressure or squeezing. The fixed capacity in such known Quetsohkondeatoren is formed from a loose alternating connection of HetaUbelegoagen with insulating material, the sum of the purposes of the capacity to be insensitive to pressure feet together or let down. Such a structure of the feature capacity within the capacitor combination has the disadvantage, however, that a sufficient constant of the fixed capacity cannot be achieved. Since the capacity, which can be changed by means of pressure, is summed up as similar ^{:. :} .. ^: Layering of metal coverings and insulating material directly

Nooh to the underlying festkapasltät, ie ·, the assignments of the fixed capacitor are trots existing Yer- j ^l. ~ · ^ sohraubung Ternletung or more or less susamaengepreast. In this case, with the unexpected change in the variable capacity, an undesired change in the fixed capacity also occurs.

The subject of the fire is a Queteoh capacitor, which also consists of a combination of a variable capacity with a fixed capacity arranged underneath, in which but no longer an undesirable change in the fixed capacity Kltät with nooh so strong, on the assignments of the changeable Capacity acting pressure can cause squeezing. To this Purposes consists of the used inside the capacitor combination Feetkapasltät from, for example, a mica plate on which On both sides the capacitor assignments are either firmly glued on as thin metal foils or, what is nooh better, by means of a Metal sputtering or metal spray process can be applied.

■ - ■> - ■ Such a fixed capacitor let kapasltlr against pressure or / · practically insensitive to bruising, it only needs to be combined in suitable catfish with the peripheral capacitance ·

^Y 'Xn of the figure is represented in the principle, for example, of a combination of this type of a Quetsoh capacitor. On a base 1 made of insulating material there is also a metal foil or metal plate 2, which is not used as a capacitor layer but only to make contact. It stands old, of a metal coating 3 "in a fixed capacitor that is practically insensitive to Druok and Quetsohung, which is formed by metallization on both sides (3 and 4) of a dö Isollersohioht 5, for example an Ollaaer plate. This fixed capacitor represents the main part of the capacitance of the Quetsohkondensatoro, it is placed in the simplest way with its one metal layer 3 on the contact surface, while the other metal layer 4 of the fixed capacitor is connected to another metal layer 6 above it stands. This metal coating 6 also serves to make contact, and it is the connection with one coating 4 of the test capacitor, but the rest also forms a capacitor coating on the actual pinch capacitor, which can be changed by means of a printer. The other covering of the condenser, which can be ragged at a small distance, is formed in a manner known to us by a stable metal plate 7 bent upwards at one end, which is placed over the metal covering 6 with an insulating layer 8 in between let. The upper metal plate 7, the distance between which can be regulated by means of the pressure socket 9, has a metallic connection with the lowest metal coating 2 of the capacitor combination and also represents the connection for the one feed line of the capacitor combination has to be done on the metal assignment 6 su.
