How do touch dimmers work?
(From: Neil). Touch dimmers work in a couple of different ways, depending on the IC used. Simple ones, such as those in the cheap ‘touch lamps’ that you find for sale on market stalls, etc. normally have three or four preset brightness levels and an OFF setting, which are operated sequentially: touch once for full brightness, again to dim slightly, again to dim a bit more, etc, until the OFF setting is reached. The next touch will then bring the lamp to full brightness. The better (and more expensive) units, such as the touch dimmer switches that are sold as direct replacements for conventional light switches, are similar, but have many more steps. A single touch will usually bring the lamp to full brightness, while keeping your finger in contact with the touch plate will slowly dim the lamp. You just remove your finger when the lamp is at the required brightness level. Both kinds of touch dimmer have three basic parts; 1. A touch sensor – this normally works by picking up mains hum fr
