Magnetic microcontactor and mfg. method thereof
The process is for mfg. a microswitch which includes a flexible beam (5) made with one or several layers of conducting material (13,14,15). This beam has one end (4) solidly attached to an insulating substrate (1) via a foot (3), and a distal end (6) which is freely positioned above a contact pad (2...

| Zusammenfassung: | The process is for mfg. a microswitch which includes a flexible beam (5) made with one or several layers of conducting material (13,14,15). This beam has one end (4) solidly attached to an insulating substrate (1) via a foot (3), and a distal end (6) which is freely positioned above a contact pad (2) formed on the same substrate. The foot (3) and the contact pad (2) are made of conducting material and are provided with connections to an external electronic circuit. The beam is made at least in part of a ferromagnetic material in order to respond to the presence of a magnet. All sections of the switch are formed by galvanic growth, using a series of masks to achieve the required overall format, with the masks being removed after construction. |
