DEFINITION

Classification: 335/228

(under subclass 220) Subject matter including means to convert the motion of the armature into an effective motion of a different type.

(1) Note. This subclass includes means, such as cams, screws, gears or other mechanical movement means to convert, for example, a reciprocal motion of a plunger type armature to a useful rotary motion.

73, for motor actuated contacts utilizing eccentric or cam actuator.

110, and 122+, for multiple contact type electromagnetically actuated switches with motion conversion means.

140, for step-by-step switch with ratchet and pawl actuator.

189+, for switch contact actuator utilizing mechanical linkage. 261, for plunger type armature structure or material.

272, for rotating armature type electromagnet.
