<p>A variable speed toggle switch that allows a user to reverse a rotational direction of a motor and supply variable amounts of power to a motor, such as in a power tool, for example, a power drill. A trigger can include a gear segment that meshingly engages a gear on a potentiometer to electrically communicate the actuation direction and actuation amount of the trigger to a microprocessor. The microprocessor can then signal to an H-bridge, or to a series of transistors, the actuation direction and actuation amount of the trigger. A motor or other device can be powered by a power source in an amount corresponding to the actuation amount, and in a direction corresponding to the actuation direction of the trigger.</p> |
