Measuring Arrangement And Measuring System, In Particular For A Liquid Sensor
A measuring arrangement includes a first magnetic switch having a first contact and a second contact, and a second magnetic switch having a first contact and a second contact. A first evaluation terminal is connected to the first contact of each of the first magnetic switch and the second magnetic switch. A first resistor is arranged between the second contact of the first magnetic switch and the second contact of the second magnetic switch. A second evaluation terminal is connected to the second contact of the first magnetic switch. A third evaluation terminal connected to the second contact of the second magnetic switch.

LIMIT SWITCH AND ASSOCIATED METHOD
A limit switch is provided. For example, a limit switch may include a housing assembly defining an upper chamber, a lower chamber, and a dividing plate defining a passage between the upper chamber and the lower chamber, a plunger selectively movable relative to the housing assembly, a magnet affixed to a lower portion of the plunger, and a sensor mounted within the lower chamber positioned to interact with the magnet to detect movement of the plunger. A width of the middle portion of the plunger is wider than the passage such that the dividing plate limits movement of the plunger away from its upward-most position. A length of the lower portion of the plunger is selected such that the lower portion of the plunger does not contact a bottom of the lower chamber when the middle portion is in contact with the dividing plate.
