Hairpin dip switch

Used to be able to get a dip switch which consisted of two shaped pieces of wire per switch.
One part, the fixed part was in a shape of a hook so that the movable part could be forced downwards beneath the hook and would be retained closed contacting the hook.
The spring tension was sufficiently high to create a gas tight contact between the two parts of the switch according to the data sheet.
In order to engage or disengage the procedure was a bit more involved than simply toggling or sliding the slider.
It would fit in conventional 0.3" pitch array.
A hint of where it might be found would be appreciated.

There's more value if you figure it out yourself!

I remember them, but haven't seen one in 20 years.
Any reason you're not interested in the more recent DIP switch offerings?

I also remember them. Maybe the O.P. wants them because they are both washable in production and cleanable in service? OTOH, if as I suspect, the contacts are plated spring steel, rust may be an issue in humid environments.

I also recall seeing them occasionally 'soldered' - once the initial configuration / resets had been completed.

I seem to think they were a Siemens product.
It takes a certain effort to engage and disengage a contact forcing the brain to engage along the way.
The corrosion is a possibility but the image is of one such item assembled way back in early eighties ( say 83 ) no corrosion so far.
