Abstract
A test apparatus for testing of a stop mechanism on a saw includes a support arm movable relative to a blade of the saw from a first position to a second position. The test apparatus also includes a simulation member coupled to the support arm. In the first position, the first end of the simulation member is offset from a portion of the blade of the saw, and in the second position, the first end of the simulation member is adapted to be in contact with the portion of the blade of the saw. The test apparatus further includes circuitry operatively connected to the simulation member to replicate an electrical property of a human finger such that contact between the blade and the first end of the simulation member triggers the stop mechanism of the saw.
