Power tool with protected coupling plate
First Claim
1. A power tool assembly comprising:
- a drop arm assembly movable along a drop path between a first drop arm assembly position whereat a portion of a shaping device supported by the drop arm assembly extends above a workpiece support surface and a second drop arm assembly position whereat the portion of the shaping device does not extend above the workpiece support surface, the drop arm assembly includinga capacitive coupling plate bracket formed from a non-conductive material and connected to a drop arm frame, anda capacitive coupling plate mounted to the capacitive coupling plate bracket;
an actuating device configured to transfer a force to the drop arm assembly when the drop arm assembly is at the first drop arm assembly position; and
a control system operably connected to the capacitive coupling plate and configured to control the actuating device to transfer the force to the drop arm assembly when an unsafe condition is sensed.

Abstract
A power tool assembly includes a drop arm assembly movable along a drop path between a first drop arm assembly position whereat a shaping device portion supported by the drop arm assembly extends above a workpiece support surface and a second drop arm assembly position whereat the portion does not extend above the workpiece support surface, the drop arm assembly including a capacitive coupling plate bracket formed from a non-conductive material and connected to a drop arm frame, and a capacitive coupling plate mounted to the capacitive coupling plate bracket, an actuating device configured to transfer a force to the drop arm assembly when the drop arm assembly is at the first drop arm assembly position, and a control system operably connected to the capacitive coupling plate and configured to control the actuating device to transfer the force to the drop arm assembly when an unsafe condition is sensed.
