Slide switch and Push Button interfacing with Spartan3e FPGA Development Kit

 Slide switch

 Slide switches are most common used in electronic circuits for digital input of ON/OFF states. They allow control over current flow in a circuit. You’ll usually find slide switches in SPDT or DPDT configurations.

 Push Buttons

 Push-button switches are the classic momentary switch. Typically these switches have a really nice, tactile feedback when you press them.

 Interfacing Slide Switch and Push Button with Spartan3e FPGA Development Kit

Push Button interface is straight forward. One end of Push Button connected to FPGA and another end connected to ground. Slide switch interface to FPGA is Pulled High by default at open end and another end is connected to ground which act as OFF State.
