摘要

PURPOSE: A switch for magnet is provided to improve productivity by reducing manufacturing time and manufacturing costs in assembling a lead switch including a glass tube. CONSTITUTION: An either side contact terminal(1130) of a lead switch(1100) has a glass tube(1120) accepting a contact point(1110) in a vacuum condition and it is located on the top of a wire fastening terminal(1200). The contact terminal is fixed to the wire fastening terminal. The lead switch and the wire fastening terminal are settled on a base core(2100) of an insert molding(2000). The glass tube and the contact terminal including the contact point and contact point are accommodated inside of the device. A base member(1300) comprises a penetration hole(1310) and a ring(1320). A signal wire(1400) is leaded into the base member.
