As in the keyboard with gaskets-caps, the closure of the contacts occurs when the walls of the three-layer membrane are in contact, but the plastic scissors are responsible for holding the key in the designated place. The scissor assembly comprises a first scissor blade, a second scissor blade, and a pivot pin pivotably coupling the first scissor blade to the second scissor blade. A scissor lift having upper and lower platforms and actuated by a cable reeved so as to pull at least one set of the ends of the scissor together at its extended position and also reeved about a cam roller interposed between the arms and working toward the pivot connection during the portion of the motion in which the lift begins to extend. It’s a machine because it helps you do work. Definition of scissors 1 : a cutting instrument having two blades whose cutting edges slide past each other 2 a : a gymnastic feat in which the leg movements suggest the opening and closing of scissors A pair of scissors consists of a pair of metal blades pivoted so that the sharpened edges slide against each other when the handles (bows) opposite to the pivot are closed. If the decision is made to lag the lift to the floor, the base frame of the lift has pre-drilled holes for lagging the lift. View Mechanism Description S18.docx from ENCS 282 at Concordia University.
