PROBLEM TO BE SOLVED: To exactly protect an electric circuit part even if used in an environment where the humidity, chlorine concentration and the like are high, and to make better the assemblability of movable components such as a magnet, a spring and a pressing means. SOLUTION: The detection switch 10 comprises a read switch 14 which is housed in a switch case 11A having an opening 11a1 on one side in a state where the switch 14 is connected to lead lines 12A, 12B, and is shield-fixed in the switch case 11A by an insulating resin 19 filled and solidified via the opening 11a1, a magnet which is movably assembled on the other side of the switch case 11A and can approach/retreat into the lead switch 14, a spring which is arranged on the other side of the switch case 11A and biases the magnet toward the retreating position, a switch lever 17 which can press the magnet to an adjacent position against the biasing force of this spring, and a push bottom 18.
