Abstract

PURPOSE:To reduce consumption of an electrically conducting liquid and to extend the life of an electrically conducting liquid switch by providing a movable contact point with taper so that a contact surface area of the movable contact point is smaller than a fixed surface area relative to a movable piece. CONSTITUTION:A movable contact point 17a is formed in a truncated cone shape having tapers on its sides to have a constant point surface area smaller than a fixed surface area thereof with respect to a movable piece 15 with Pt-Ni alloy to be easily wetted with an electrically conducting liquid 18 (mercury) and is covered with a film of the electricity conducting liquid on its entire surface. As a result, at the instant when the movable contact 17a collides with a magnetic pole section 10, the amount of the electrically conducting liquid 18 pushed out around is small and small droplets are less likely to be produced and the amount of splash is drastically reduced as the electrically conducting liquid 18 pushed out also moves to the sides of the contact point. This prevents the reduction in the amount of the liquid 18 for wetting the fixed electrode and extends the life of the switch.
