A switch hinge is described having a first hinge wing, which accommodates a switch operable by a lever, having a second hinge wing and having a shaft which, in the operative position, is non-rotatably connected with the second hinge wing. The shaft, on its circumference, has a switch groove which extends in the direction of the shaft axis and into which an operating pin connected with the lever dips in a predetermined swivelling position between the two hinge wings. In a preassembled condition, in which the operating pin rests in the switch groove, the shaft is secured by a lock against rotation with respect to the first hinge wing, and the second hinge wing is freely swivellably with respect to the shaft. A screw screwed into the face-side end of the first hinge wing axially displaces the shaft by a predetermined extent out of the preassembled position into the operative position. The shaft has a knurled or otherwise structured ring zone which, when the shaft is displaced in the operative position, is press fitted into a hinge bore of the second hinge wing, for achieving the securing against rotation between the second hinge wing and the shaft. Subsequently, the rotational lock of the shaft to the first hinge wing is removed.

A safety switch includes a switch housing which accommodates a switch as well as mechanical and electrical and electronic components, and a head portion securable to an end face of the switch housing in several predetermined angular positions and accommodating a mechanical switching element e.g. a switching wheel which is operated by an actuator. A rigid positioning element is detachably secured to the switch housing and formed with a safety member, whereby the positioning element is adjustable between a locked position in which the safety member is positively engaged in the head portion and an idle position in which the safety member is disengaged from the head portion for allowing a rotation and re-positioning of the head portion relative to the switch housing.

A quick-action tensioning device (1) for cable control switches comprises a holding element (2), to which a cable (3) can be fastened in a clamping manner, and a housing (8), which is connected with the holding element (2). According to the invention, devices (9, 10) for a precise adjusting are provided between the housing (8) and the holding element (2). In particular, a nut (10) can be used for the precise adjusting, so that the cable tension can be continuously adjusted, in which case a rough adjustment as well as a precision adjustment can be carried out.

A safety switch includes a spring-biased locking pin which is displaceable axially inside a switch housing by a lifting magnet against the biasing force of the spring to switch a switching element between a blocking position and a release position, and a retention magnet which holds the locking pin in the release position when the lifting magnet is de-energized.

A safety switch including a spring-loaded tappet axially displaceably disposed in a switch cover; a switching bridge on the tappet; and an actuator above the tappet. An essentially U-shaped element has a center web and a first and second leg. The element is swivellably disposed in the cover in the area of the center web and the first leg of the element engages the tappet. The second leg is situated above the tappet such that when the actuator has moved in, the second leg reaches behind and engages the actuator in a switch-on position and permits a complete pulling-out of the actuator from the cover only in a switch-off position.

A radius actuator including an actuating member having a shaft which projects into the holder and carries the ball on that end. The ball is fixedly clamped into a clamping part which consists of two halves connected with one another by screws and which is situated in a hollow chamber of the holder. A spring is between the clamping part and the holder in the hollow chamber. The holder is provided with two mounting bores which lead into the hollow chamber and are alignable with the screws of the clamping part.

A manually operable, electrical operating member having two key buttons for the respective switching-on and switching-off of the current, which key buttons are arranged on mutually opposite sides and can be operated in several steps. A common, mechanically operable switch is provided with which the key buttons are each in an operative connection.

A housing structure, includes a compartment body formed by interconnecting side walls and a door, and hook-shaped hinges for articulating the door to one side wall. The side wall is formed with a groove which extends longitudinally from top to bottom. Each hook-shaped hinge exhibits an angled section and extends through a slot of the door for engagement in the groove, with the angled section of the hinge at least partially overlapping a marginal area adjoining an outer edge of the door.

A terminal box includes a base and a cover detachably securable to the base. The cover is provided with a stepped bore in each corner area thereof, with a spring-loaded locking bolt being insertable therein and slideable in axial direction in opposition to the spring action for securing the cover to the base. Each locking bolt has one end provided with a blade-like expansion which is created through flattening this respective end of the locking bolt. In the area facing the base, the cover is provided with radial slots which are in alignment with radial slots of the base and suitably dimensioned to receive the blade of the locking bolts. When placing the cover upon the base, each locking bolt is pressed down through the bore and radial slots in the base and turned to allow the blade of each locking bolt to bear upon an abutment of the base for securement of the cover to the base.

A switch device, includes a casing having an inlet opening for introduction of a conductive cable, having at least two conductors and an insulating sheath. The casing has an open end which is closeable by a lid. Received in the interior of the casing are contact members having terminals which point in the direction of the lid, for penetration through the insulating sheath of the cable and contacting the conductors. A pressure pad is secured interiorly on the lid in an area of contact-making between the contact members and the conductors, for exerting a pressure onto the cable, whereby the pressure pad so projects into the interior of the casing as to firmly press the cable onto the contact members via the connected terminals, when the lid is closed.
