Abstract
This invention provides an electromagnetic relay formed on a substrate (1), preferably a multi-layer printed circuit board. The magnetic circuit (4, 5, 6a, 6b, 7a, 7b) passes through holes (2, 3) in the substrate, and is formed using printed circuit manufacturing techniques, such as electroplating to manufacture the plated through holes. The armature 7b is formed by depositing the armature material on a temporary layer, which is then removed.
Claims22
A micro relay device including a magnetic path formed of a movable armature at least partly of magnetizable material the magnetic path including magnetizable material carried by a support member, the support member including one or more through holes to permit the magnetic path to pass from a first side of the support member to a second side, the armature being proximate to the first side, the magnetic path extending along or proximate to the second side.
A micro relay device including a support member, a movable armature attached at one end to a first plated through hole in the support member, a fixed contact attached to a second plated through hole in the support member, and a magnetic path between the plated through holes on a second side.
A method of fabricating a cantilever or overhanging member on a substrate, the method including forming a removable layer of a first material, forming a member of a second material on the removable layer, and removing at least part of the removable layer.
A relay array in which each of the relays are addressable by at least two current paths, wherein a first current in first current path energizes, but does not trip a first plurality of relays, and a second current in the second current path energizes, but does not trip a second plurality of relays, the relay to be operated being common to the first and second pluralities, the aggregate of the first and second currents being sufficient to trip the target relay.
A relay in which the coil of each relay is divided into two or more sub-coils, wherein each sub-coil can be energised individually, the current in each sub-coil being limited so that the force of one sub-coil is insufficient to activate the relay, and wherein the additive force of two of the sub-coils is sufficient to activate the relay.
A relay array substantially as herein described with reference to the accompanying drawings.
A method of manufacturing a relay array substantially as herein described with reference to the accompanying drawings.
A micro relay device including a support member, first and second through holes containing magnetic material and traversing first and second sides of said support member, at least one fixed contact on said first side, a moving armature formed at least partly of magnetic material located proximal to said first side, a magnetic return path located proximal to said second side and at least one electrical activation path located within or on the surface of said support member.
