<p>PURPOSE:To enable the assembly of a reed switch to be easily performed, by mounting the reed switch onto a printed substrate having a lead wire, in the case of a check valve equipped with a flow switch providing the reed switch closed by approach of a magnet provided in a valve main unit. CONSTITUTION:A device mounts a magnet 26 to the point end of a valve guide 25 of a valve main unit 23 while provides a built-in reed switch 29, closed by approach of the magnet 26 by moving upward the valve main unit 23, in a part opposed to the magnet 26 of a base 28. The device, mounting the switch 29 onto a printed substrate 20 connecting a lead cord 37 further inserting said printed substrate 30 into a recessed part 28b in the base 28, enables the reed switch 29 to be mounted to a check valve by one-touch action.</p> |
