Abstract
A PCB assembly can be attached to hold one or more such assemblies. A resilient PCB housing holds a PCB by an interference fit while conductive wires are inserted into its wire cavity so that exposed portions of conductive wires make electrical contact with electrical traces of the PCB which is biased by wire insulation. Two conductors can be held by the PCB housing which are forced into electrical contact with the PCB when it is inserted into the resilient PCB housing which then biases such contacts. A switch can also be held by a switch interference fit with the resilient PCB housing such that its leads are biased against the PCB by the resilient PCB housing.

An electrical assembly, comprising:
- a first block housing;
- a ribbon block;
- a printed circuit board (“PCB”) having a surface with a plurality of electrically conductive elements located between a first end of the PCB and a second end of the PCB;
- and
- a ribbon wire assembly held within the ribbon block by an interference fit;
- wherein the ribbon wire assembly is comprised of one or more wires having an insulated covering with a stripped portion at an end thereof;
- wherein the first block housing and the ribbon block are connected by a snap fit to form a completed assembly which holds first and the second ends of the PCB;
