摘要： The invention relates to a low voltage switchgear with a bimetallic actuator, especially to a motor safety switch or a power switch. The aim of the invention is to improve such a low voltage switchgear so that the fabrication and assembly tolerances are widely compensated for. To this end, the two-part (21, 22) housing (2) of the switchgear (1) is provided with an opening (23) that is closed with a protective cover (24). By way of said opening (23), the bimetallic component (51) and the jack system are accessible for the purpose of measurement and a bridge system (52) of the bimetallic actuator (5) that is calibrated on the basis of the measured values can be mounted therethrough.

摘要： The invention concerns a contact system having fixed and moving contact parts for an electromagnet switching device with a switching magnet, which is accommodated in a housing and has an armature, and with an instantaneous release device with striking pins. The movable contact parts are mounted on a contact bridge which is mounted in a contact carrier, connected to a push rod, so as to move against the pressure of a compression spring mounted in the contact carrier. The push rod with the contact carrier is coupled for movement with the armature of the switching device switching magnet. The striking pin of the instantaneous release device acts on the contact bridge in order to lift the movable contact parts off the fixed contact parts. In the release state of the instantaneous release device the striking pin thereof can be clamped to the push rod bearing the movable contacts and can be detached by the lifting movement of the push rod, whereby the contacts can be closed again.

摘要： The invention relates to a contact system for a low-voltage switch device that comprises per main conducting path a movable contact bridge (2) with movable contact elements (4; 6), mounted on a contact carrier bridge (18), a pair of stationary contact elements(8; 10) with stationary contacts (12; 14), and an auxiliary magnet system (22) with a magnet coil (24) disposed in the main conducting path. A retention element (32) mounted in the switch device prevents the contacts from being unintentionally electrodynamically opened. Said retention device is actuated by the armature (28) and connected to the contact bridge (2) so as to retain it independent of the further state of the auxiliary magnet system (22).

摘要： The invention relates to an electric safety switch device (1), especially a protective motor switch, comprising a housing (12) consisting of duroplastic, a switching contact arrangement, a release device with at least one bimetal release, a release bridge that acts upon a switch latch and can be operated by the bimetal and a support for components (5). Said support consists of an insulating material. Various contact and connection components of the release unit can be pre-assembled on said support for components (5). The aim of the invention is to easily assemble the inventive device and to guarantee a stable bimetal position. To this end, the contact and connection components of the release unit are glued together in the housing (12) or in a part (13) of the housing and are fixed in the housing without an additional connection, whereby said components can be pre-assembled.

摘要： The invention relates to a protected switch (1) with a housing (6) and a rotatable control grip (3) securable against switching on by at least one padlock. A cover (2) large enough to cover the control grip (3) and lockable by means of the padlock(s) is foldably fitted to the housing (6). In the cover (2) there is a recess (22) into which the control grip (3) can be received. The recess (22) can be set to its off position in accordance with the position of the control grip (3) with the contacts of the protected switch (1) fully open and the control grip (3) can be received into the recess (22) in the cover (2) only in its off position, and the cover (2) can be moved into the closed position, where it can be locked by means of the padlock(s) only with the control grip in the off position.

摘要： The invention relates to a protective switch, in particular a power or motor protective switch, with a locking device (6) to prevent switching-on of the protective switch (1) by padlocks suspended in locking openings (60) which can only be cleared when the switch contacts of the protective switch (1) are completely open. The locking device (6) has a blocking device to prevent switching-on movement of the actuating handle (3), and a release device for the locking openings (60) which comprises a slide (61) and a disc (4) operatively connected to an operating shaft (5). Said disc prevents the slide (61) from moving when switch contacts are not completely open. The actuating handle (3) is freely rotatable on the operating shaft (5), and the disc (4) is connected to the operating shaft (5) and is free from play. The actuating handle (3) and the disc are operatively connected to each other by at least one flexible claw (42) with the result that rotation of the actuating handle (3) is transferred via the flexible claw (42) to the disc (4) and subsequently to the operating shaft (5), and the slide (61) acts on the disc (4) to block the switching-on movement of the operating shaft (5).

摘要： The invention relates to a circuit-breaker which is activated by rotation and which has a leading auxiliary switch. When the circuit-breaker is switched on, the auxiliary contacts of the auxiliary switch (4) are activated temporally before the main contacts. The invention provides for an actuator element (6) containing a driving pinion (20) which is rotation-activated by an actuating mechanism (8) and a first gear rack (21) which is arranged in such a way that it can be moved longitudinally. Said first gear rack (21) engages with the drive pinion (20) and activates the auxiliary switch (4). A second gear rack (22) and an associated output pinion (30) are also provided, said second gear rack (22) being lag-connected to the first gear rack (21) in the direction of switching on (27). Said output pinion (30) is connected to an actuating shaft for the breaker mechanism of the circuit-breaker (2). The tooth pitch of the output pinion and the second gear rack (22) is greater than the tooth pitch of the drive pinion (20) and the first gear rack (21) to the extent that the overall angle of rotation of the drive pinion (20) and output pinion is constant for the entire switching-on movement of the actuating mechanism (8).
