Claims

[Scope of utility model registration request]

(1) An elongated main permanent magnet with magnetic poles formed on both end faces in the thickness direction, a pair of elongated yoke parts arranged on the magnetic pole faces of the elongated main permanent magnet, and one of the pair of elongated yoke parts. a magnetic member comprising a bridge portion bridging a part of the longitudinal edge of the elongated yoke; and a switch mechanism interlocked with the auxiliary permanent magnet; The permanent magnet is attracted to the longitudinal edge of the elongated yoke part when it is in a position facing substantially in front of the bridging part, and is in a position not facing substantially in front of the bridge part. The slide switch device is characterized in that when the elongated yoke portion is moved, the elongated yoke portion rebounds against the longitudinal force-directed edge portion and separates.

(2) The sub permanent magnet has a single-sided two-pole structure, and has an N pole facing the longitudinal edge of the N pole side yoke portion of the Lee permanent magnet. The slide switch device according to item 1. (3) The sub permanent magnet has a structure in which magnetic poles are formed on both end faces, and has an N pole facing the inner surface of the longitudinal force direction edge of the N pole side yoke part of the main permanent magnet. A slide switch device according to claim 1 of the utility model registration claim.
