In the electromagnetic switching device, it is possible to miniaturize and
have low costs, have quiet operation noise, and also quickly extinguish
the arc. The electromagnetic switching device has an electromagnetic
actuator with a movable iron core, a pair of fixed terminals that
respectively have a fixed contact point, a movable contact that has
movable contact points on the right and left ends, a shaft, and an
enclosing component that holds the movable contact points and the fixed
contact points. The pair of movable contact points respectively contact
with and detach from the pair of fixed contact points, and the pair of
fixed contact points respectively conduct each other and are insulated
again through the shaft by moving the movable iron core along the axis
using the electric magnetic actuator. A quasi-hermetically sealed space,
which is the extinguishing space, is formed by the enclosing component
and a first yoke. A potting compound is charged, into the space between a
body and the quasi hermitically sealed space.
