  • Publication number: 20140210647
    Abstract: A switch assembly is disclosed having a switch with an actuator moveable from an armed position to a disarmed position. A housing is attached to the switch and contains a cam that holds the switch actuator in the armed position. A trigger makes contact with the cam causing it to rotate within the housing and allowing the actuator to extend to move to a disarmed position. In some variants the cam can be shaped to prevent manually rotation against the bias force of the actuator in the disarmed position. The switch assembly can be positioned on an aircraft landing gear to detect an over-steer occurrence where the landing gear may become damaged. The state of the switch can be visibly or audibly indicated by an indicator in the aircraft cockpit or other location visible/audible to the ground operators.

  • Patent number: 8657556
    Abstract: A tactile wafer lifting apparatus includes a pedestal and a vertical drive connected to the pedestal. The vertical drive is defined to provide controlled upward and downward movement of the pedestal. The tactile wafer lifting apparatus also includes a wafer support member disposed over the pedestal. A tactile switch is disposed between the wafer support member and the pedestal such that sufficient downward force on the wafer support member causes activation of the tactile switch. The tactile switch is connected to the vertical drive so as to interrupt upward movement of the pedestal and wafer support member disposed thereover upon activation of the tactile switch.
