I need 2 or maximum of 3 switches in my bread board experiment. In future I may be required more than 3. So should I buy 8 in 1 DIP switches, or separate sets of 3, 4, 5 DIP switches etc keeping economy factor in consideration. Also can I use jumper wire or some other thing instead of switch. Electronics and IC Market is more than 100 miles away. I have to perform logic gates and latches on breadboard. I have all other apparatus.
