    摘要： A two position indicating device including an indicator member in the form of a rotor that carries a single permanent magnet and is mounted for rotation between two limit positions which are determined by engagement of spaced-apart portions of the rotor with the end of a pole piece of a stationary electromagnet structure. The electromagnet structure comprises a combined bobbin and rotor support, the rotor support having two spaced ears and the rotor being rotatably mounted to the spaced ears by detent means comprising a hole in each ear and two pins carried by the rotor. Attachment and removal of the rotor is achieved by flexing the two ears apart far enough to release the two rotor pins. A coil is wound around the bobbin and terminal means are provided for energizing the coil to selectively establish first and second electromagnetic fields of opposite orientation for effecting movement of the rotor between its two limit positions.

    摘要： A two-position indicating device including a rotatable indicator member that carries a single permanent magnet and is mounted so that it can rotate between two limit positions determined by a single pole piece of a stationary electromagnetic structure. The electromagnetic structure may comprise either one or two coils wound around the pole piece for establishing electromagnetic fields to effect movement of the indicator member between the two limit positions. The rotatable member is adapted to provide different indications in the two limit positions. A modification of the invention includes a permanent magnet associated with the electromagnetic structure to restore the rotatable member to a given limit position.
