Query: selector switch failed quickly

I normally turn this lamp on and off using a wall switch, only occasionally using the switch on the lamp to select between 50w, 100w, or 150w output on the 3-way bulb. After very little use, the lamp switch failed. The part you grab still rotates, but nothing happens inside. Luckily it is stuck in the 150w position which is the one I use most. But I cannot recommend this lamp.
