Sir,
I Want To Control One Lamp From 6 Switches
Its Possible Please Suggest Me

 

Your request needs a bit more detail.

Is is safe to assume that you are looking for an arrangement in which there are 6 switches located at various places within a room so that if the lamp is off you can flip any one of the switches and turn the lamp on and then with the lamp on you can use any one of the 6 switches to turn the lamp off?

I'm not sure it's what you're after, but if you google for '"four way switch" wiring' you'll get diagrams wherein any switch can toggle a light, with an arbitrary number of switches possible.

 

Look for "four way switched circuit" at http://www.act-solutions.com/PCC/kingery07.htm

You can use 5 XOR gates that control one relay. The relay controls the lamp. Just cascade the XOR gates like this:

RLY
|
XOR
| |
XOR \
| _| _\
XOR XOR XOR
| | | | | |​

The switches can control the gate inputs. TTL is good for that application, as the inputs won't float in case of contact failure.
