Table saw with linkage drop system

A table saw comprising:

• a work-piece support surface;
• a swing arm assembly movable along a swing path between a first swing arm position whereat a portion of a shaping device supported by the swing arm assembly extends above the work-piece support surface and a second swing arm position whereat the portion of the shaping device does not extend above the work-piece support surface;
• a first link arm with a first tracking component and a first slot, the first tracking component slidingly engaged with the swing arm assembly;
• a second link arm with a second tracking component engaged with the first slot;
• an actuator configured to pivot the second link arm from a first position whereat force from the first link arm acting on the tracking component is directed at a second link arm pivot toward a second position whereat force from the first link arm acting on the tracking component is not directed at the second link arm pivot;
• and
• a control system configured to actuate the actuator in response to a sensed condition.
