The circuit is using two different ICs, which are a 555 timer and other is a CD4017 IC. The circuit is having two different parts, the first part is a capacitive sensor built with a 555 timer IC and the second part is a relay sequencer built with CD4017 decade counter IC. Any voltage from 5V to 12V can be applied to the circuit, the relay values should be used according to the operating voltage.
Here is a project of a touch activated sequence switches circuit. The circuit is having six relay switches, which can be activated one by one by touching a single touch plate or point. The circuit can be used to activate six separate electronic appliances connected separately with each relay
