Abstract
A lever arm adapted to hold a stylus or the like on one end is rigidly connected at the opposite end in spaced parallel relation to a second arm, and a shaft perpendicular to both arms through the rigid connection provides a pivot axis therefore. An opening in each arm in registered relation, at equal distances from the shaft, receive tabs on opposite edges of a plate-shaped pivoting armature which suspend it between the two arms and position it in a diagonal neutral position in a gap between two axially opposed, individually switched solenoids, each having a contact area and diagonally opposing abutments for contacting the armature biased against them in neutral position by at least one spring, whereby actuation of the solenoids moves the arms to three different stable positions.
