Tapping electromagnets are also quite common in everyday life, primarily used in products such as printers, copy machines, and coin-operated telephones. In terms of shape, they are more complex than frame-type electromagnets. The tapping electromagnet is a combination of suction cup electromagnets and push-pull electromagnets, integrating the characteristics of both. Through the magnetic field generated by the coil and the fixed iron core, one end of the lever plate is attracted down, while the other end lifts up. Just like a seesaw, this achieves a distribution function.

From a professional standpoint, the working principle of the tapping electromagnet consists of a reciprocating carriage, a track rod, and a small tapping arm mechanism. The tapping arm is mounted on the reciprocating carriage, which is powered by an electric motor, a cam shaft, and tension springs on the carriage. The wheels of the reciprocating carriage are mounted on the track rod, powered by electricity, and can reciprocate within any interval of the track rod.
