| Disclosed is a magnetic contactor. A free space in which a DC converting circuit is provided is in a product can be secured by changing shapes of the movable core and the fixed core, and thus, in association with a low-capacity product, external AC power may be converted into DC power even without enlarging a size of a product. Also, a normal position member may be included in a movable core, and may induce the movable core to the original position, and thus, a mechanical mechanism relationship between the switch manipulating part included in the movable core and the other element is maintained. | ||||||

| A safety switching device, with which a safety-related device, can be set into a safe state. The safety switching device has a microprocessor or microcontroller, which can set an electric drive to be protected into a safe state both if an emergency circuit breaker, protective door switch, and/or two-hand switch is activated and also if there is faulty operation of the safety-related device or electric drive.

In addition, the microprocessor can be a component of a safety device which is constructed for multiple-channel control of a safety-related electric drive. In this way, the safety switching device can respond to several safety functions independent of each other in order to set an electric drive into a safe state. | ||||||

| The invention relates to a safety switching device, with which a safety-related device, preferably an electric drive, can be set into a safe state. The safety switching device (900) has a microprocessor or microcontroller (822), which can set, for example, an electric drive to be protected into a safe state both if an emergency circuit breaker, protective door switch, and/or two-hand switch is activated and also if there is faulty operation of the safety-related device or electric drive. For this purpose, the microprocessor (822) is preferably implemented such that it can determine from at least one analog signal to be measured whether a predetermined parameter, preferably the amplitude of the analog signal, lies outside a predetermined operating range. In addition, the microprocessor (822) can be a component of a safety device (810) which is constructed for multiple-channel control of a safety-related electric drive. In this way, the safety switching device (900) can respond to several safety functions independent of each other in order to set an electric drive into a safe state. In addition, for such a compact safety switching device, the risk of a wiring error relative to known measures is significantly reduced. | ||||||

As a result, the terminal connection conductors are collectively surrounded by the insulation case to protect the insulation. At the same time, the terminal connection conductors are connected to an electrical device in a unitized manner, thus preventing wrong wiring operation when they are connected. | ||||||
