Touch Switch Circuit Diagram Using Ne555. Touch switch using ne555 posted by circuit diagram in switch and relay circuits the series of touch switch or touch switch is built by ic ne555 a series of touch switches can be used to turn on lights alarms or other electronic equipment. Here we take a look at some 555 timer circuits based on the ic.
This circuit is based on a passive infrared pir sensor which automatically switches on a device when someone comes close to it. Touch lamp circuit using ne555 timer. Here the ic is configured as an monostable multivibrator in this mode the ic activates its output momentarily by producing a logic high in response to a trigger at its input pin 2.
The circuit works well in a range of 5 to 15 volts.
In circuit uses an integrated circuit timer lm555 or ne555. This is the circuit diagram of a small touch plate controller using ic ne 555 this circuit is ideally useful for making touch operated doorbells buzzers toys etc which when touched on the touch plate operates the relay for a preset time and then turns off automatically. Touch switch circuit using 555 timer. The circuit works well in a range of 5 to 15 volts.
