Abstract
A battery holder for use in conjunction with a coin type battery carries an electric element having a pair of leads extending radially of the inner surface of the holder. One of the leads is considerably longer than the other and extends to the edge of the holder and then turns axially along the inner surface of the rim of the holder so as to engage the side edge of a coin battery when inserted. A substantial portion of the remainder of this lead is covered by insulation material so as to prevent contact with other portions of the coin battery. The other lead from the electric element engages a terminal of opposite polarity of the coin type battery when the coin type battery is properly inserted so as to switch the electric element to an "ON" state. Reversal of the battery orientation switches the element "OFF".
