Hairpin dip switch
IconicPCB:
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.

I remember them, but haven't seen one in 20 years.
Any reason you're not interested in the more recent DIP switch offerings?
Ian.M:
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.
SL4P:
I also recall seeing them occasionally 'soldered' - once the initial configuration / resets had been completed.
