Brand logos

The following SVG images are my own work. Each one is created based on a photograph, scanned document or similar. Most are approximate due to the limited resolution, quality and accuracy of the source material, along with the sometimes considerable variation in form of the logos.

Please note that most if not all of these logos are—or at least were at the time—trademarks or registered trademarks of the respective companies.

Possibly a Ukrainian manufacturer; found on some ПКМ 1Б reed switches (very approximate reconstruction)


The Alps logo is derived from a print advertisement in Electronic Engineers Master 1983, with corrections for ink spread based on careful observation of some accurately-moulded switches. The design seems to have varied quite a bit over time.

The black-on-white RFT logo is derived from the Passive elektronische Bauelemente ’79|80 catalogue. Both RFT logos are rough approximations due to a present lack of high resolution image to use as a basis, as well as the usual lack of consistency from one version to another. The red EB logo uses also a rough guess at the colour.
