This is the electronic unit which senses the human flesh touching the blade, and activates the heavy spring loaded chunk of aluminium, jamming it into the saw blade. The unit costs about $100, and the saw blade is invariably wrecked, with teeth being knocked off. But hey, would you rather lose a finger or a hand? I am told that if the unit is actually activated in preventing an injury, that Sawstop will replace it free of charge.  The unit can only be fitted to machines which are designed for it.  It cannot be retrofitted to older machines.
