Title: Pierre Lemarquand: Innovator in Electromechanical Switching Technology
Introduction
Pierre Lemarquand is a notable inventor based in Dijon, France. He has made significant contributions to the field of electromechanical switching technology, holding a total of 7 patents. His work focuses on developing innovative switching apparatuses that enhance functionality and safety in electrical systems.
Latest Patents
Among his latest patents, Lemarquand has developed a "Switching apparatus with contacts controllable by an electromagnet." This electromechanical switching apparatus is particularly designed for protection applications, where the contacts can be controlled by a locally or remotely operated electromagnet. The electromagnet is of the monostable type, and an engagement mechanism is associated with a mobile assembly connected to the mobile armature. A two-position switch, accessible from outside the case, enables or disables the operation of the engagement mechanism. Additionally, an auxiliary closure piece is provided for manual closure of the contacts.
Another significant patent is the "Protective switching apparatus with remotely controlled opening and closing." This apparatus includes a tripping mechanism connected to an assembly comprising at least two fixed contacts and two mobile contacts, along with a magnetic and/or thermal trip. It features a resetting member and an electromagnet with a movable element, which drives at least one pseudo-fixed or mobile contact. The mobile contacts are carried by a bridge that has a plane of symmetry, and the tripping mechanism extends in the vicinity of this plane.
