摘要 |
The present invention is directed to a switch device that includes an actuator guide coupled to the switch actuator plate. The perimeter wall of the guide is disposed within the back body member in a nesting arrangement such that the actuator guide is configured to slide within the back body member in a substantially linear motion between a non-switch actuating position and a switch actuating position. The perimeter wall forms a contaminant shield to substantially prevent dust external to the device from contaminating the plurality of guide portions. A transmission mechanism is coupled to the actuator guide and configured to convert the linear motion of the actuator guide into a rotational movement when the switch actuator plate is depressed. A mechanical switch mechanism is configured to move between a first switch state and a second switch state in response to the rotational movement of the transmission mechanism.
