KBK update for Tuesday, 15th October

Deepak Kandepet has taken a series of photos of the Alps SCK variant that appeared to be double pole–capable. This has throw up a few surprises. Firstly, it is single pole: the extra terminal holes are seemingly not usable.

More interestingly, it appears to be a lost motion design that offers hysteresis, apparently based on Datanetics DC-50. It may also be the switch type that was classified KCA.
