ABSTRACT:
A portable power angle tool includes a housing and an operating head for performing work on a workpiece. A power source supplies energy for the operating head and a switch mechanism includes a switch for interrupting the flow of energy to the operating head as well as an angle lever for actuating the switch. The angle lever is mounted on the housing and the arms of the lever extend outwardly away from the bottom of the housing. The lever can be rotated by the operator to a first position whereat one of the lever arms actuates the switch and a second position whereat the lever arms of the angle lever conjointly support the tool on the rest surface. The weight of the tool bearing down on the angle lever tends to hold the lever in its second position when the tool is set down to rest by the operator on the rest surface thereby substantially minimizing the danger that a person stepping on the tool could inadvertently turn on the tool and cause either injury to himself or damage to the workpiece to be worked. In addition, by configuring one of the lever arms as a paddle disposed close to the rest surface, additional safety is obtained because the operator will have to first obtain control over the tool before he can get his fingers beneath the paddle.
