Mechanism 120 comprises a selector switch 122 slidably coupled to the tool 100 and disposable in one of a first and second positions, which may relate to first and second rotation directions respectively. The selector switch having first and second end portions, with recesses (132 figure 3) formed in switch 122 therebetween. Mechanism 120 also having a non-contact actuator 124 disposed in one of the recesses(132) of the selector switch, and a non-contact sensor 126 adpated to detect the proximity of the non-contact actuator 124. The actuator 124 may include one or more of a magnet, a hall sensor, or a light source. The non contact sensor 126 may include one or more of an inductive sensor, a capacitive sensor or a light sensor.

Mechanism 120 comprises a selector switch 122 slidably coupled to the tool 100 and disposable in one of a first and second positions, which may relate to first and second rotation directions respectively. The selector switch having first and second end portions, with recesses (132 figure 3) formed in switch 122 therebetween. Mechanism 120 also having a non-contact actuator 124 disposed in one of the recesses(132) of the selector switch, and a non-contact sensor 126 adpated to detect the proximity of the non-contact actuator 124. The actuator 124 may include one or more of a magnet, a hall sensor, or a light source. The non contact sensor 126 may include one or more of an inductive sensor, a capacitive sensor or a light sensor. 非接触式方向选择机构 方向选择机构 120 使工具 100 的电机能够选择性地沿第一方向或第二方向旋转。 该机构 120 包括选择开关 122，选择开关 122 可滑动地联接至工具 100，并可置于 第一位置和第二位置中的其中一个位置，第一位置和第二位置可以分别对应第一旋 转方向和第二旋转方向。该选择开关具有第一端部和第二端部，两端部之间在开关 122 中形成有凹部（图 3 所示 132）。机构 120 还具有设置于该选择开关的其中一 个凹部（132）中的非接触式致动器 124，和适于检测非接触式致动器 124的接近度 的非接触式传感器 126。致动器 124 可以包含磁体、霍尔传感器或光源中的一种或 多种。非接触式传感器 126 可包括电感式传感器、电容式传感器或光传感器中的一 种或多种。
