摘要：A switching apparatus has a cylindrically shaped hollow insulated body with firstand second parts that sealingly engage each other at longitudinal abutting surfaces. Thefirst part has a longitudinal recess. The body is formed with a radial button retainingpassage. A conducting unit is disposed in the recess and includes elongated first andsecond conducting elements with a respective first end portion contacting a

corresponding one of two input terminals of a driven element, and a respective secondend portion. The second end portion of the first conducting element contacts one of twooutput terminals of a power source. A third conducting element has a first end portionextending out of the body and contacting the other output terminal of the power source,and a second end portion spaced apart from the second end portion of the secondconducting element. A button unit is movably disposed in the button retaining passage. Aconducting contact member is mounted on the button unit and is pushed by acompression spring to contact the second end portions of the second and third

conducting elements so as to activate the driven element. A retaining unit is employed tobreak selectively electrical contact among the second and the third conducting elementsand the contact member against action of the compression spring.
