Abstract
A trigger switch assembly comprises a housing; a plunger coupled with a trigger and moveably mounted within the housing along an actuation axis; a magnet moveably disposed within the housing; a displacement mechanism disposed within the housing and operable to displace the magnet with a movement of the plunger such that a first travel distance of the plunger translates to a second travel distance of the magnet that is smaller than the first travel distance; and a magnetic sensor disposed within the housing, wherein the magnetic sensor is operable to output a signal associated with a location of the magnet.

A trigger switch assembly comprising:
- a housing;
- a plunger coupled with a trigger and moveably mounted within the housing along an actuation axis;
- a magnet moveably disposed within the housing;
- a displacement mechanism disposed within the housing and operable to displace the magnet with a movement of the plunger such that a first travel distance of the plunger translates to a second travel distance of the magnet that is smaller than the first travel distance;
- and
- a magnetic sensor disposed within the housing, wherein the magnetic sensor is operable to output a signal associated with a location of the magnet.
A power tool, comprising:
- a main body having a handle portion;
- an output supported by the main body;
- a motor, supported by the main body, and operable to rotatably drive the output;
- and
- a trigger switch assembly supported by the handle portion, the trigger switch assembly including:
- a housing;
- a plunger coupled with a trigger and moveably mounted within the housing along an actuation axis;
- a magnet moveably disposed within the housing;
- a displacement mechanism disposed within the housing and operable to displace the magnet with a movement of the plunger such that a first travel distance of the plunger translates to a second travel distance of the magnet that is smaller than the first travel distance;
- and
- a magnetic sensor disposed within the housing, wherein the magnetic sensor is operable to output a signal associated with a location of the magnet.
