Sealed reed contact switch with permanent magnet - has reed contact(s) in plane parallel to switch rocker but spaced from its motion plane

摘要

Each sealed reed contact of the switch is arranged in a plane parallel to the switch rocker movement plane. This two planes are of such spacing that at least in one end position of the switch actuator or the rocker the rocker part containing the permanent magnet is in direct vicinity of one of the sealed reed contacts. The opposite ends of the eccentrically mounted rocker contain the permanent magnet and a counterweight respectively. The rocker may be mounted in swivelling manner on a shaft, secured in opposite sides of the switch housing, possibly with a spiral spring between the shaft and the rocker. This spring may be adjusted from outside through a slit in the housing.
