1. A dimmer comprising:
a sole intensity actuator structured to be actuated between a maximum light intensity and a minimum light intensity by a user, and is further structured to be used for at least one of:
adjusting light intensity based on a first user input during normal operation; or
entering configuration mode based on a second user input; and
adjusting an end trim value based on a third user input;
a sole intensity potentiometer mechanically coupled to the sole intensity actuator and comprising a variable resistor, the sole intensity potentiometer structured to measure an input voltage based on variable resistance, wherein the variable resistance changes based on a position of the sole intensity actuator corresponsive to the first user input, the second user input, or the third user input; and
a controller coupled to the sole intensity potentiometer and a driver circuit coupled to a bidirectional switching device, the controller structured to control dimmer operation comprising receiving a signal indicative of the measured input voltage from the sole intensity potentiometer and transmitting a dimming signal to the driver circuit for driving the bidirectional switching device, the dimming signal based at least in part on the signal.
