PROBLEM TO BE SOLVED: To provide a switching arrangement and a component for it, wherein superior dustproof function for contact parts can be ensured, and an adhesive sheet can be set so as to have a comparatively small shape and size. SOLUTION: In this switching arrangement, a pressure-sensitive adhesive sheet, composed of a cover sheet 1 provided with a dome-shaped movable contact 3 capable of making contact with and separating from a stationary contact 8 and a spacer sheet 2, is stuck on a printed board 6 having the stationary contacts 7, 8, non-adhering parts 2b-2e provided so as to extend in a direction of separating from the center part of the dome-shaped movable contact 3 are provided in the spacer sheet 2, and a second air escape part 10, communicating with a first air escape part 9 formed around the dome-shaped movable contact 3, is formed between a surface part on which the stationary contacts 7, 8 of the printed board 6 are disposed and the non-adhering parts 2b-2e of the cover sheet 1 and the spacer sheet 2.
