This is a very simple touch light switch circuit that uses the 4011 IC, one transistor and a relay. The C1 capacitor stores the switching state at a certain time and is charged or discharged according ...

Simple touch switch circuit with 4011 – source. The circuit as you can see from its diagram is very simple and only uses 8 components. The heart of the circuit is the IC CD 4011 that is connected as a ...

Lamp switches can be kind of a pain—either you can't reach them comfortably, they break within a few months, or they just take a lot of force. With an inexpensive touch switch, you can turn any ...

Touch the tester’s probe to the wires on the switch. If the electricity is off, the tester will not light up or emit an audible beep. However, if the tester lights up or beeps, then the power is ...

Jacob Kastrenakes is The Verge’s executive editor. He has covered tech, policy, and online creators for over a decade. One of the biggest challenges facing smart home gadgets is the light switch ...

Smart switches are often part of a smart home system and commonly control both the power state (on/off) and brightness of your lights through an app or voice command. Style wise they look very much ...

This PLL-based circuit implements a touch-switch circuit using the PC board or small metal pads as sensors; it is radiometric and thus insensitive to changes in temperature and supply voltage ...

Either kind might pose a problem with some touch lamps. Lighting consultant Terry McGowan said that if a touch lamp has a mechanical switch, it will work with any CFL or LED bulb.
