Abstract
A rotary power tool having a tool housing, an internal housing within the tool housing, and a switch assembly that is substantially within the tool housing. According to the invention, the switch assembly is supported by the internal housing and is movable between at least two positions for selecting between at least two tool operational modes. The internal housing is embodied by at least one blocking element that extends towards the tool housing and limits the overall range of motion of the switch assembly.
Claims27
A rotary power tool having an axis of rotation comprising:
- a tool housing;
- an internal housing within the tool housing;
- and
- a switch assembly that is substantially within the tool housing, supported by the internal housing, and movable between at least two positions for selecting between at least two tool operational modes,
- wherein the internal housing has at least one radially-extending blocking element that extends towards the tool housing and limits an overall range of motion of the switch assembly, and
- wherein the switch assembly has an extension extending from the switch assembly in a direction of the axis of rotation that is blocked by the at least one blocking element.
A rotary power tool having an axis of rotation comprising:
- a tool housing;
- an internal housing within the tool housing;
- and
- a switch assembly that is substantially within the tool housing, supported by the internal housing, and movable between at least two positions for selecting between at least two tool operational modes,
- wherein the internal housing has first and second blocking elements that extend towards the tool housing and limit an overall range of motion of the switch assembly, the first blocking element and the second blocking element together delimiting the overall range of motion of the switch assembly, and
- wherein the switch assembly has an extension extending from the switch assembly in a direction of the axis of rotation that is blocked by the first and second blocking elements.

- wherein the internal housing has at least one blocking element that extends towards the tool housing and limits an overall range of motion of the switch assembly,
- wherein the switch assembly has a switch outer portion and a flexible switch inner portion which changes shape when the switch assembly is moved between the at least two positions, and
- wherein the flexible switch inner portion is substantially ring-shaped and has a ring diameter which increases as the switch assembly is moved between the at least two positions to provide additional clearance for adjusting the switch assembly so that the switch assembly overcomes retaining structure on the internal housing.
