BI-DIRECTIONAL TAMPER RESISTANT TEMPERATURE DIAL |
摘要 |
A bi-directional tamper resistant temperature adjustment controller interface comprises a control dial having an interior face wherein a cylindrical center boss extends therefrom, said cylindrical center boss having a substantially annular cross section, and a central axial bore adapted to receive a rotatable control member and an exterior side wall of the boss has formed therein a first and a second ring of inline recessed notches adapted for resistively engaging a deflecting member. In one embodiment of the invention the first and second ring of inline recessed notches are a first and second ring of directional serrations wherein the first ring of serrations are angularly directed in a first direction to resist rotation of the dial in one direction of rotation and the second ring of serrations are angularly directed in a second direction to resist rotation of the dial in an opposing direction of rotation.
