Abstract
A motion detector, in particular suitable for animals, comprising at least one motion element, wherein an element movable within a predetermined area is located, which brings about an electrical connection in at least one position, wherein the movable element is a magnetic element, which can move along a path of travel formed by a cavity in the motion element, and wherein, near the path of travel, at least one magnetically sensitive switching element is placed, which can be influenced by the magnetic element.
Claims28
A motion detector, in particular suitable for animals, comprising at least two electrical switching elements and at least one motion element in which at least one element movable within a predetermined area is located, wherein each of the switching elements can be excited depending on the position of the at least one movable element within the at least one motion element, characterized in that at least one of the switching elements acts as a reset switch for at least one of the other switching elements, characterized in that the motion detector is provided with an electronic circuit which is connected with the switching elements and which is arranged such that said action as the reset switch is obtained;
- characterized further in that the electronic circuit is arranged for registering an excitation of one of the other switching elements only when, prior to this excitation, an excitation of the switching element acting as the reset switch has taken place.
