<p>Disclosed is a contact-action switch structure, comprising a magnetic control switch (10), an electronic element (20), and a power source (30), wherein the magnetic control switch comprises: a switch sleeve (11) that is an electrically conductive sleeve, exhibiting a tubular shape in the interior, and divided by a step shape into an upper combination end (111) and a lower combination end (112) provided with an upper opening and a lower opening respectively; an insulation sheath (12) located inside the switch sleeve for electrically insulating elements in the inside and outside of the insulation sheath; a magnet (13) of annular shape having a central hole, located inside the insulation sheath; a T-shaped shaft (14) having a long shaft (141) and a head (142), with the long shaft passing through the central hole, and the size of the head being larger than that of the central hole; and an electrically conductive package cover (15) in the shape of a cup having an opening, having electric conductivity and located in the insulation sheath; one electrode of the electronic element is connected to the front end of the long shaft of the T-shaped shaft and the other electrode thereof is directly or indirectly electrically connected to the switch sleeve; and one electrode of the power source is connected to the electrically conductive package cover and the other electrode thereof is directly or indirectly electrically connected to the switch sleeve. Hence, the stability of a switch circuit is enhanced, and more space for a pen head is able to be saved to accommodate electronic elements having various functions in the pen field.</p> |
