du Bois-Reymond style switch

(Schlüssel nach du Bois-Reymond)
Description: This switch makes contact by pushing a wire into a mercury cup and makes this contact very precisely and without the contact burning, a difficulty which is common to any metal-to- metal contact in a relay or other switch. (Expanded caption Copyright 1998, Edward J. Haupt)
