Variable fixed voltage supply

In this simple project we are generating 4 DC supplies for different purposes. These 4 DC supply have different values of voltages depending  upon the switches are ON or OFF. By using this circuit we can generate 4V, 3V ,2V and 1V DC supply.
         See the circuit we used 8 resistors and 4 switches. We get different voltage levels at point V1,V2,V3 and V4. We get output at these points according to the given table. See the conditions when only one switch is ON.
