Abstract (en)
[origin: US4400671A] A mercury wetted switch, controlled by a magnetic field produced from a discret semiconductor encapsulating box or case, whose base has a double or so-called "common" electrode and at least one other insulated electrode. A moving plate engages in fork-like manner in the double electrode and bears against another electrode. The liquid wetting the contacts forms a liquid hinge for the plate on the double electrode. Application to electrical relays, particularly for professional equipment and telecommunications.
