KBK update for Thursday, 8th August

Finally my Micro Switch SW Series models 1SW201-R and 1SW204-R switches arrived from the US. These are exactly what I hoped they would be: the elusive “bi-level” (double-action types). Double action in SW Series is achieved not with two sensors, but with a larger sensor IC with two Hall elements integrated. The stage two springs are attached to the plunger and protrude down from it, making contact with the switch mounting frame.

The sensor in these switches is type “U”.
