ABSTRACT:
A dual in line switch apparatus selects between several switch positions. A housing has several slides. A row of terminals is attached to the housing. A contact sheet is located between the slides and the terminals. The contact sheet operates, as the slide is moved, to make and break electrical connections between the terminals. The contact sheet includes a flexible film having a contact pad and a detent notch and an adhesive tape that is attached to the flexible film. The tape has a slot formed therein and the contact pad is pressed through the slot by the slide to electrically connect with the terminals. The switch provides electrical contacts that are sealed from detrimental environmental effects. The detent notch provides a positive mechanical stop with tactile feedback for each of the switch positions. An alternative embodiment uses another flexible film with conductive vias that connect to solder spheres.
