ABSTRACT:
An electrical magnetic switch adaptable for use in a digital wristwatch in which a command function for a digital wristwatch is controlled by a switch or an actuator. The magnetic switch is normally open and is closed by the movement of the wrist of the wearer to overcome the magnetic force from a permanent magnet on a magnetizable movable armature. The displacement of the magnetizable movable armature against the urgency of the magnetic force closes a circuit for performing a command function for the digital wristwatch. For regulating the magnitude of force on which the magnetizable movable armature is displaced against the urgency of the magnetic force of the permanent magnet, means are provided for adjustably positioning the permanent magnet relative to the path of travel of the magnetizabe movable armature. Alternatively, the movable armature may be a permanent magnet and the adjustably positioned means may be made of magnetizable material.
