definition
limit switches have different names. Thus, the terms position switches, limit switches or limit switches apply to them. But

characteristics of the Schlegel-limit
behind all these terms a switching device, which is used primarily for the protection of people and machines. These limit switches have a wide range of actuators which should be selected according to the respective actuation. They are used for switching auxiliary and control circuits and are ideal for the control and movement control of z. B. processing machines, elevators, conveyors, vehicles, building, crane systems, as well as trigger switch in safety and signaling systems and much more. The individual types are designed for different operating and environmental conditions. Therefore, different housing materials for the respective limit switches are offered. In order to meet the various circuit requirements, there are a variety of contact combinations that can provide almost all mechanical circuit variants. A plurality of drives, which are displaceable in each case by 90 °, also enable a good adaptability to the particular application case.

arrangement, operation and actuation of the limit switch
switch and plunger drive should only be used when the switching point is closely tolerated. The operation should be carried out preferably in the same direction of movement as that of the tappet. The limit switches are designed so that they may not be used as a mechanical stopper. The restoring force for additional movable actuators (dampers, doors, etc.) may not be removed from the drive of the limit switch, since the restoring force is designed for the provision of the limit switch plunger. To ensure an optimal switching operation, the specified maximum of the individual drives to be considered. The cam must actuate the plunger only in the permitted level. The blowout of the driving device may only according to the relative diagram. It is not permissible to shorten by actuating the driving the power stroke. The return movement must be guided by the cam itself, d. H. the drive should not spring back freely to its rest position.
The length of the actuating cam must be chosen so that operation time with 2-fold safety is achieved. Is as the response of the operated contactor relay to the self-hold 15 ms, the minimum actuation time

mounting of the limit switches
limit should ms be the limit switch 30th are easily accessible and shock-proof in accordance with the aforementioned to assemble evidence. To ensure the specified degree of protection, the cover screws must be tightened evenly and tighten the cable gland according to the cable diameter appropriate.
The use of the limit switches must be made in compliance with the specified parameters and in the instruction. Depending on the switching frequency and operating conditions, the equipment at regular intervals must be checked for their reliability.
