Abstract
A trigger assembly can be used to activate a motor controller to cause a motorized device to respond in a certain manner. For example, when the motorized device is a power tool, based on a number of pulls of the trigger, the motor controller can run the power tool in a forward direction or a reverse direction. A power tool running in the forward direction can receive a tap of the trigger. A timer can be started upon detecting the pull of the trigger. Another tap of the trigger can be detected within a time period determined based on the timer. The power tool can be forced to perform a reverse operation when the other tap f the trigger is within the time period.
