MAGNETIC TYPE PROXIMITY SWITCH PROVIDED WITH MAGNETIC CORE COIL

PURPOSE: To provide a magnetic type proximity switch provided with a magnetic core coil capable of reduction in size and cost and provided with a magnetic type proximity switch provided with a magnetic core coil capable of reduction in vibratory component current. CONSTITUTION: A magnetic core coil 2 to which a drum type magnetic body 21 having an open magnetic passage constitution can be applicable is used as a magnetic proximity switch 1 against the conventional instance. The positional relationship in mutual arrangement between a lead switch 8 and the magnetic body 21 is positioned by making a shaft line K3 in the direction of aligning the centers of a pair of conductor bodies 81, 82 coincide with a plane P2 on which the central shaft line K2 of the magnetic body 21 possessed by the magnetic coil 2. In addition, axial line K8 is so arranged that a size difference l81 may be approximately zero in relation to the central part in the longitudinal direction of the magnetic body 21 and may cross the central axial line K2 of the magnetic body 21 at approximately right angles.
