A low profile, push-pull, jumper switch that relies on movement of an electrically-insulating switch housing to make and break the connection between two contact members mounted on the surface of a PCB or other substrate. The only metal used are the two contact members and a fixed wire in the housing. The wire is forced into contact with the contact members to electrically interconnect them by movement of the housing when placed in its closed-switch position. In a preferred embodiment, the two contact members are identical and are each constituted of a one-piece U-shaped metal member, with the U-bight depending from the housing and configured to be solderable to the PCB pads or through-holes and thus being fixed. The contact members are configured to latch the housing in its open-switch position or closed-switch position. The switch lends itself to SMT applications.
