Abstract
A hold-and-release device for the movable lower guard of a hand-operated circular saw in which the guard is held in its out-of-the-way position by a magnet or latch while a saw cut is being made but is automatically released to assume its normal protective position when the motor power is removed. Alternatives are described having different degrees of complexity, for example, one requires the operator to apply pressure to the trigger switch while engaging the guard-holding device.
