    Not good for low voltage application as silicon residue will just attract dirt. Silicon maybe used to lubricate or shield from oxidants or seal from cathodic reaction, but most of the times they are for high current applications like battery terminal and moving contacts. It may even not be wise to use them in dissimilar metals ie copper and aluminum as the physics says one metal becomes sacrificial anode hence accelerating the decay and eventually the silicon paste becomes a suspension of green and white jelly dirt..

    Use appropriate electronic contact cleaner like CRC brand. Most ordinary contacts are either lead coated or copper, for low voltages and sensitive parts its gold-plated (for corrosion resistance). Sometimes a semi oxidized electronic contact maybe cleaned with pencil eraser and dry cloth.

    If you just want to lubricate the plastic/rubber locks,slides, slots of the connector then its fine, i'd recommend silicon paste as the spray leaves a white or yellow powdery residue. Spray is better on weather stripping and hard-to-reach rubber/plastic areas.
