Abstract: An electromagnetic relay for consumers with a high switch-on current peak has a main contact and a preliminary contact on legs which extend near one another. The legs carrying the main and preliminary contacts are connected at both sides with another leg via connecting webs and have each a stretch zone between a common connecting yoke of the legs and the connecting webs. At the stretch zones the main and preliminary contacts are adjusted independently of one another by means of squeezing the material of the contact carrier.

Abstract: An electromagnetic relay has a base plate, a magnetic yoke mounted on the base plate, a relay winding, a spool core supporting the relay winding, a hinged armature arranged turnably on the spool core, a switching contact supported on the hinged armature, a counter contact cooperating with the switching contact, an adjusting part adjusting a contact distance between the countercontact and the switching contact when the armature is retracted and having at least one stretching zone extending substantially in a movement direction of the armature, the adjusting part forming a lever having a free end cooperating with the switching contact and another end anchored on the base plate, and an adjusting web provided with the stretching zone and engaging at a location between the ends with the adjusting part, so that by extension of the adjusting web to adjust the contact distance at the free end of the adjusting part.

Abstract: An electromagnetic relay comprising a magnet yoke having a coil core for supporting a relay winding and a support for supporting a folding armature at one end of the folding armature; and a leaf spring for biasing the folding armature away from the coil core in a non-operating position of the relay, the leaf spring including a curl surrounding the support and having two fastening portions at which the leaf spring is fastened to the magnet yoke and the folding armature, respectively, and a prestress area between the two fastening portions.

Abstract: An electromagnetic relay comprising a hinged armature pivotably supported at a front face of a coil core carrying a relay winding, a switching contact supported on the hinged armature, a fixed counter contact cooperating with the switching contact for actuating the electromagnetic relay, and contact carrier for supporting the fixed counter contact and having a first portion including a center leg and two outer legs arranged on opposite sides of the center leg in spaced relationship relative thereto, a crossbar connecting the center and outer legs at one end thereof, the center leg having at an end thereof spaced from the crossbar a bent-away portion for supporting the one fixed counter contact, the first portion further including in the vicinity of the bent-away portion of the center leg laterally symmetrically extending webs for connecting the center leg to the outer legs, respectively, the center leg having a stretchable portion located between the crossbar and the connecting webs for adjusting a posiiton o

Abstract: To reliably prevent ingress of moisture to a connection between an electrical connecting cable or line to an electrical apparatus within a housing, the conductors of the cable or line are externally surrounded by an insulating layer which is of such a material that it joins, by melting or chemical reaction with the material of a surrounding bushing or sleeve, which bushing or sleeve then can be secured in a wall of the apparatus, for example by a removable rubber ring (FIG. 2) or can be molded into the housing of an electrical apparatus, for example a sensor; preferably, the materials of the housing and of the plug or sleeve also join, either by melting together or by chemical reaction. For a melt connection, a thermoplastic such as polyamide is suitable; for reactive connection, a reactive thermosetting plastic, for example polyester imide, or epoxy may be used.

Abstract: The invention concerns an electric measuring instrument with a connecting cable, preferably an inductive bar sensor for measuring the speed of rotating bodies, which emits electric signals in relation to the rotational speed of the body. To allow that the manufacturing and testing of the measuring instrument (10) can be carried out as economically as possible, the measuring device preferably consists of two prefabricated components (27, 28) joined in such a way that they are interlocking and moisture-proof, namely the actual measuring device consisting of a coil (13), a coil form (14), a permanent magnet (17), a flow conductor piece (15), a pole shoe (16), conductor rails (18) and a housing (20), and a connector piece (25) embedding the end of the connecting cable (22) with the conductor ends (23). Such measuring instruments (10) can be used in motor vehicles or in industry, as temperature probes, pressure sensors, rotational speed sensors or speed sensors for rotating bodies, etc.

Abstract: An insulating cup-shaped body (29) that is screwed into the rim (11) of a vehicle wheel prevents conduction of heat (generated by the brakes, for example) from heating the metallic body (16) that forms a reference pressure chamber closed off by a membrane (17) from the inflated interior of a vehicle tire. The membrane (17) is set slightly within the rim of the cup for protection during tire changes. The chamber and switch housing (16) and a spool (27) for the coil of a resonant circuit form a preassembled unit that is snapped into the insulating cup and cemented into place. The relatively large coil diameter adds to the economy of the device, permitting the use of a small capacitor. The temperature of the gas sealed in the reference pressure chamber (18) by closure of the filling bore with a steel ball (25) follows the temperature of the interior of the tire and reliably opens the resonant circuit if the tire pressure falls below a prescribed limit.
