What is the Debouncing?
Bouncing is the tendency of any two metal contacts in an electronic device to generate multiple signals as the contacts close or open; debouncing is any kind of hardware device or software that ensures that only a single signal will be acted upon for a single opening or closing of a contact.
Switch debouncing is one of those things you generally have to live with when playing with switches and digital circuits. If you want to input a manual switch signal into a digital circuit you'll need to debounce the signal so a single press doesn't appear like multiple presses.
- At only $39.99, with a one year contract, it is the cheapest option. After your 12 months contract ends, the plan changes to $59.99 a month; bringing the total cost of two years of an Internet Only package with Comcast to $1,199.76 or $49.99 a month, on average, over 24 months.

- 30mbps is not blazingly fast by today's standards, but it is also very adequate. 1080p streaming takes 5–10mbps, and 4k around 16mbps. So you will not have issues streaming video, which is the most demanding task for a typical home connection.
Definition. When a mechanical switch or relay closes, the switch elements will often bounce, even if only briefly, before making final contact. This is of consequence if downstream elements are sensitive to the switching transients. A contact debouncing circuit is often used to remove the transients.
- Switches allow different devices on a network to communicate. Routers allow different networks to communicate. A router also connects networked computers to the Internet, so multiple users can share a connection. And a router acts as a dispatcher.
- An electrical switch is any device used to interrupt the flow of electrons in a circuit. Switches are essentially binary devices: they are either completely on (“closed”) or completely off (“open”). There are many different types of switches, and we will explore some of these types in this chapter.
- The types of switches are classified into four types namely:
- SPST (Single Pole Single throw)
- SPDT (single pole double throw)
- DPST (double pole, single throw)
- DPDT (double pole double throw)
