ABSTRACT:
A switching apparatus has a cylindrically shaped hollow insulated body with first and second parts that sealingly engage each other at longitudinal abutting surfaces. The first part has a longitudinal recess. The body is formed with a radial button retaining passage. A conducting unit is disposed in the recess and includes elongated first and second conducting elements with a respective first end portion contacting a corresponding one of two input terminals of a driven element, and a respective second end portion. The second end portion of the first conducting element contacts one of two output terminals of a power source. A third conducting element has a first end portion extending 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 second conducting element. A button unit is movably disposed in the button retaining passage. A conducting contact member is mounted on the button unit and is pushed by a compression 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 to break selectively electrical contact among the second and the third conducting elements and the contact member against action of the compression spring.
