Non-contact operating proximity switch

Claim 1

A non-contract proximity switch, with a direct current circuit arrangement lying between an input portion and a sensor field producing means including a terminal-side main portion set in a base housing and a sensor portion arranged in a probe, said probe being adapted to be selectively set in different predetermined positions on the base housing of the main portion for enabling a selection of a response direction, means for insulating the probe on all sides thereof, said main portion includes a direct current/alternating current transformer with a core coil, the sensor portion includes an alternating current/direct current transformer with an added core coil, and wherein the core coils are disposed behind both a fastening side of the base housing and the probe whereby, when the probe is released from inductive coupling, energy carries over from the main portion to the sensor portion and provides output signals from the sensor portion to the main portion, said probe is cube-shaped and includes a fastening side adjacent a response side thereof and fastening side disposed in opposition to the response side, and wherein a core coil is mounted on each of the fastening sides, with the core coils being attached to the same alternating current/direct current transformer
