Abstract: A switching system including a switch activation pin, a switch, and a switch connector is provided. The switch activation pin mounts to an arm that pivotally mounts a door to a body of a device. The switch activation pin moves with the arm when the door is opened or closed. The switch mounts to the device to control a component of the device. The switch connector mounts to the device to activate the switch based on a position of the switch activation pin.

Abstract: A hinge including a device bracket, a door bracket, a first arm, a second arm, and a door stop is provided. The device bracket mounts to a device surface. The door bracket mounts to a door surface of a door. The first arm is mounted for rotation about a first pin and a second pin. The second arm is mounted for rotation about a third pin and a fourth pin. The first pin and third pin are mounted to the device bracket, and the second pin and fourth pin are mounted to the door bracket. The first pin is closer to an axis of rotation of the door than the third pin when the door is in a closed position. The door stop is mounted to the second arm and positioned to contact the first arm when the door is opened to a selected angle.

Abstract: A hinge support includes a brace, a trestle, and a positioning device. The brace includes a base wall and a first side wall, a second side wall, and a positioning wall that extend from the base wall. The first side wall has a first sloped surface, and the second side wall has a second sloped surface. The trestle includes a top wall and a third side wall, a fourth side wall, and a support wall that extend from the top wall. The third side wall has a third sloped surface, and the fourth side wall has a fourth sloped surface. The positioning device is supported by the support wall and positioned to abut the positioning wall to mount the trestle to the brace. The third sloped surface slides along the first sloped surface and the fourth sloped surface slides along the second sloped surface under control of the positioning device.

Abstract: A hinge including a device bracket, a door bracket, a first arm, a second arm, and a closure device is provided. The first arm mounts to the device bracket at a first pin and to the door bracket at a second pin. The second arm mounts to the device bracket at a third pin and to the door bracket at a fourth pin. The third pin is closer to an axis of rotation of a door than the first pin when the door is in a closed position. The closure device includes a closure device body mounted to move with the second arm, a rod mounted within the closure device body, a spring, a spring retainer mounted to the rod, and a nut mounting the rod to the device bracket. The spring is mounted between the spring retainer and the closure device body to exert a force on the second arm.
