Abstract
The invention belongs to the technical field of electronics, and discloses a capacitive touchpad parameter adjusting device comprising a capacitive touchpad module. A lower pad, at least one electrically conductive slider module and an upper pad are arranged above the capacitive touchpad module sequentially. The lower pad is provided with at least one T-shaped guide groove used for accommodating the capacitive touchpad module to slide longitudinally along the lower pad. The electrically conductive slider module comprises an electrically conductive slider, a metal elastic sheet and a PVC (polyvinyl chloride) sheet.
