ABSTRACT:
A selective switch includes a switch housing, and a button cap with two opposite side portions. A contact assembly includes first, second and third conductive members which are all fixed in the switch housing. A helical spring is mounted in the switch housing, and has an outer end portion to support the button cap thereon and an inner end portion adjacent to the contact assembly. A flexible mandrel has an inner end portion and an outer end portion which is integrally formed with the outer end portion of the helical spring. The helical spring extends around the flexible mandrel. A movable contact member is in electrical contact with and is carried on the inner end portion of the flexible mandrel to move between a first position in which the contact member is in electrical contact with the first and second conductive members in response to depression of one of the side portions of the button cap, and a second position in which the contact member is in electrical contact with the second and third conductive members in response to depression of the other one of the side portions of the button cap.
