摘要:
There is provided an add-on terminal connector assembly for electric control devices used in motor control centers that eliminates the conductor bends necessary to route incoming conductors to the terminals of a control device which is mounted in the control center.

A removable group of auxiliary switches is mounted on the upper surface (4) of the contactor housing by hinging means (28, 29) and resilient locking (32, 33) placed respectively in the area of the base (8) and of partitions (5) which separate the principal terminals (6). The group comprises two switches (make and break). Coupling in this manner makes it possible to increase the number of auxiliary switches without increasing the contactor's frontal or lateral congestion.
摘要:
An electro-magnetic relay arrangement in which a pair of spaced electromagnets are supported on a base and a pair of associated armatures are pivoted relative to the electro-magnets about aligned axes. A rigid wire connects the two armatures to extend parallel to the axes and a pair of springs biasses the armatures away from the electro-magnets, said pair of springs extending between the base and portions of the rigid wire adjacent the respective armatures.
摘要:
A relay having a C-shaped element surrounding a coil winding to provide a magnetic circuit. The magnetic circuit displaces a movable blade carrying an elongated contact having a free extremity disposed in position for contacting rest and working fixed contacts, the fixed contacts being disposed in a plane perpendicular to the longitudinal axis of the relay.

A noise-free low-power consumption wide voltage range DC and AC contactor and remote telephone control system is disclosed. A movable iron core is connected to a linkage. Another end of the linkage is connected to a micro switch. A normal close contact of the micro switch is serially connected to a magnetic coil and is parallel connected to an IC circuit and a retaining coil. A lower end of the movable iron coil is in the extent of the coil so that the magnetic coil attracts the movable iron core to move downwards to conduct the contactor and meanwhile, the magnetic coil will disconnect. The retaining coil is used to replaced the magnetic coil to attract the movable iron core. Since the power consumption of the retaining coil is small and thus the contactor is noise free, lower power consumption, and wide voltage range. Three voltage stages are selectable. The connector can be used with a telephone, a telephone wire, a voice system, a keyboard and a software program so as to be formed as a remote telephone control system with a simple structure, lower cost and be a multi-functional device. Thereby, it can be used widely.
