摘要 <p>A free-wheeling safety switch is intended for controlling a power supply for a motor and includes a linked single-throw conductor and a double-throw conductor. A fusible link is located between the poles of the conductors. A connection between the double-throw conductor and the single-throw conductor switches the conductors sequentially such that the double-throw conductor switches between its normally closed position and its switched position prior to the single-throw conductor shifting from its normally-off position to its on position. The single-throw conductor is switched from its on position to its off position before the double throw conductor switches to its normally closed position. The power supply is electrically connected to the motor only when the double-throw conductor is in its switched position and the single-throw conductor is in its on position.</p>
