Table saw with dropping blade

A table saw, comprising:

• a latch hold mechanism;
• a swing arm movable along a swing arm path
• between a first swing arm position adjacent the latch hold mechanism and a second swing arm position spaced apart from the latch hold mechanism;
• said latch hold mechanism movable with respect to the swing arm;
• a latch movable between a first latch position whereat the latch is engaged with the latch hold mechanism and the swing arm is maintained at the first swing arm position, and a second latch position whereat the latch is not engaged with the latch hold mechanism and the swing arm is not maintained at the first swing arm position;
• an actuating device configured to transfer a force to the swing arm when the swing arm is maintained at the first swing arm position resulting in a bias on the latch in a direction toward the second latch position;
• and
• a control system configured to control the actuating device to transfer a force to the swing arm when the swing arm is maintained at the first swing arm position sufficient to move the latch from the first latch position to the second latch position.
