We claim the ornamental design for the controller base and handle, as shown and described.
FIG. 1 is a first perspective view of the controller mounted in a fixture on a panel shown in broken lines (since the panel is not part of the invention), the handle being tilted upward from the base;
FIG. 2 is a second perspective view, showing the base and handle rotated relative to FIG. 1 and the handle tilted downward from the base;
FIG. 3 is a perspective side view of the handle and base;
FIG. 4 is a second perspective front thereof;
FIG. 5 is a front elevation view thereof;
FIG. 6 is a rear elevation view thereof;
FIG. 7 is a right side elevation view thereof;
FIG. 8 is a left side elevation view thereof; and,
FIG. 9 is a plan view thereof.
The bottom is devoid of surface ornamentation, so a bottom view is omitted.
The broken lines showing the panel in FIGS. 1 and 2 views is for illustrative purposes only and forms no part of the claimed design.
