1. An input device assembly comprising:
- a base;
a touch sensor; and
a scissor mechanism positioned between the base and the touch sensor and configured such that the touch sensor is moveable towards the base in a substantially uniform manner that substantially prevents tilting of the touch sensor with respect to the base, the scissor mechanism comprising;
a first arm comprising first and second end portions and first and second side portions interconnecting the first and second end portions, the first end portion of the first arm being rotatably mounted to the base, the second end portion of the first arm being slidable relative to the touch sensor, wherein the first and second end portions of the first arm are separated by a first distance; and
a second arm rotatably coupled to and positioned between the first and second side portions of the first arm, the second arm comprising first and second end portions and first and second side portions interconnecting the first and second end portions, the first end portion of the second arm being rotatably mounted to the base, and the second end portion of the second arm being slidable relative to the touch sensor, wherein the first and second end portions of the second arm are separated by a second distance, the second distance being less than the first distance,wherein the second arm of the scissor mechanism is rotatably coupled to the first arm of the scissor mechanism at a pivot, and deflection of the touch sensor causes the first end portion of the first arm to rotate relative to the base, the second end portion of the first arm to slide relative to the touch sensor, the first end portion of the second arm to rotate relative to the base, the second end portion of the second arm to slide relative to the touch sensor, and actuation of a switch mounted to the base, wherein the first arm completely surrounds the second arm upon deflection of the touch sensor.

Abstract
An input device and a method for providing an input device are provided. The input device assembly includes a base, a sensor support, and a scissor mechanism attached to the base and the sensor support. The scissor mechanism allows for only substantially uniform translation of the sensor support towards the base in response to a force biasing the sensor support substantially towards the base.
