Abstract
PURPOSE: To allow a single solenoid to set three positions for three-step operation by providing a guide member on the tip of a plunger in projection and supporting a permanent magnet with the guide member so as to move axially to the plunger.
CONSTITUTION: Where a current is not carried to a solenoid 1, a plunger 4 is pushed forward to a set position by the force of a spring 5, and a permanent magnet 10 comes in contact with the end face of the plunger 4 as indicated by (a). Where the current is carried in the direction that a magnetic pole opposite to a magnetic pole on the plunger 4 side takes place, the plunger 4 is attracted to a pole shoe 3 along with the magnet 10 as indicated by (b). Where then the current is carried in the direction that the same magnetic pole as that on the base end face of the magnet 10 takes place on the tip of plunger 4, the magnet 10 is pushed forwared through a guide member 6 by repulsion face until it comes to collide with a stopper 7 as indicated by (c). The then end face of the magnet 10 is in the second attracted position C.
