PROBLEM TO BE SOLVED: To eliminate the need of battery replacement in a transmission section which transmits an object sensing signal of object sensing means.SOLUTION: A transmission section comprises a main body part 41 in which a generator 41e is incorporated, and a movable part 42 which moves closer to and away from the main body part 41. By pushing the movable part 42 closer to the main body part 41, self-power generation is performed and a signal including a sensing signal is transmitted by power generated in such a case. The transmission section is disposed at a lower end side of a switching body 10 while turning the movable part 42 downwards and is provided to perform self-power generation by pushing the movable part 42 upwards with an object X when a lower end portion of the switching body 10 is abutted to the object X. |
