ABSTRACT:
A resilient switching device includes a casing, at least two electrically conductive pieces, and a resilient contact piece. An elastic strip having a turning zone is always deflected to a predetermined side normally. One end of the resilient contact piece is fixed at the top end of an electrically conductive piece while the other end is a free end having a conductive contact at a position corresponding to a conductive contact of another electrically conductive piece. When a user pushes either end of a depression key to move the resilient contact piece clamped at the gap upwards or downwards, the upper or the lower end face of the gap would depress down or prop up the turning zone of the resilient contact piece to result in a connection or disconnection between a first conductive contact and a second conductive contact to thereby effect an electric “ON” or “OFF” state.
