Abstract
Abstract Flat-type contact relays are produced by an automatic procedure employing a small number of parts. The contact spring planes are fabricated from plates of elastic or flexible insulating material. Conductor leads corresponding to the contact springs are deposited on these plates by a printing or etching procedure. The plates have embossed areas which facilitate piling, stacking, adjusting and fixing the plates to one another and to the relay core.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
166 words
A contact spring arrangement for electromagnetic multicontact relays employing cores and armatures of magnetically conductive material, comprising a relay core, a plurality of flexible plates of insulating material, means for fastening said flexible plates at one end to the relay core to hold them substantially parallel to the core and to each other, conductor leads deposited on said flexible plates to represent the contact springs, reinforcements provided for the flexible plates of insulating material to separate them by an amount corresponding to the selected spacing of the contacts in the opened condition, said reinforcements of the flexible plates of insulating material consisting of elevated portions and grooves of the same type, extending in the longitudinal direction of said conductor leads, and the conductor leads extending through said grooves and within the range of the contact-making being arranged by being staggered by one quarter of the distance of the center lines of adjacent grooves, in relation to the side and to the own position within the groove.
Claim 2
Dependent Claim
166 words

Claim 3
Dependent Claim
25 words
A contact spring arrangement according to claim 1 in which the contact leads are deposited on both sides of said flexible plates of insulating material.
Claim 4
Dependent Claim
16 words
A contact spring arrangement according to claim 2 in which said conductor leads include reinforced portions.
Claim 5
Dependent Claim
27 words
A contact spring arrangement according to claim 1, in which the flexible plates of insulating material are slotted within the range of contact-making between adjacent conductor leads.
Claim 6
Dependent Claim
63 words
A contact spring arrangement according to claim 1, in which parts of said conductor leads serving to complete an electric circuit are deposited in a spaced relation on the flexible plates of insulating material such that the plates of insulating material as arranged on top of each other are capable of being plugged into one another for establishing the connection with printed circuits.
Claim 7
Dependent Claim
56 words
A contact spring arrangement according to claim 1 in which straps or land portions and resilient clips are provided, by which the spacings and the contact pressures between the flexible plates of insulating material as actuated by the armature, and the neighboring plates of insulating material within the range of contact-making are capable of being adjusted.
