PURPOSE:To take the connection of a reed switch to a coaxial cable into consideration and to reduce the loss, by supporting one magnetic rod of the reed switch at an insulator block so as to provide the freedom in the axial direction only, and connecting the rod to an inner conductor of a coaxial cable. CONSTITUTION:The reed switch 11 is inserted to the inside of a driving coil 13, the outside is covered with a case 14 in common use for an outer conductor of metallic cylinder having printed boards 15, 15' and fixed to a metallic fixture 16 via the printed boards 15, 15'. The magnetic rod 11a of the reed switch 11 is soldered to a pattern 15a formed on the printed board 15, the inner conductor 19a of the coaxial cable 19 led externally is soldered to the pattern of the printed board 15 for electrical connection with the rod 11a. The other magnetic rod 11b of the reed switch 11 is supported to the insulator block 18 fitted to the metallic fixture 16 so as to be free axially and soldered to the inner conductor 19a' of the other coaxial cable 19'. |
