Abstract:
A switching device comprising:a circuit board having a plurality of holes;a DIP switch having a plurality of selectors provided parallel to each other and the DIP switch being secured on the circuit board;a housing for enclosing the circuit board having a first opening disposed corresponding to the selectors; anda metal cover having a second opening corresponding to the selectors, a plurality of risers extending from each of a first, a second, and a third sides enclosing the second opening, and a plurality of pins on the second and third sides extend downward;wherein the DIP switch is in contact with the metal cover by inserting the pins into the holes, the risers are urged against the housing such that the DIP switch is enclosed by the metal cover, the housing, and the circuit board with the first and second openings left as an only passage between the DIP switch and outside of the housing and a portion of the circuit board under the DIP switch is obstructed from the outside thereby preventing a first EMI generated by other electrical elements on the circuit board from interfering with the DIP switch as well as preventing a second EMI generated by the portion of the circuit board under the DIP switch from being emitted out of the first opening.
