A case for defibrillator electrode pads on a release liner is described which protects the pads prior to use and retains them in either an electrically connected or electrically disconnected configuration. When the case is closed, spring contacts on opposite sides of the inside of the case retain the pads and release liner in place. The retention either holds electrical conductors in contact with each other to retain the pads in electrical connection with each other, or in a different configuration in which the pads are not electrically connected.
