You can find a datasheet for the 4017-types IC here. However, there are many other manufacturers that still make this little IC, and they are often pin compatible. They do not produce this IC anymore, so this actual type is obsolete. This is a decade counter/divider made by STMicroelectronics. The basic of our circuit will be the HCF4017BE. First we will see how the switches behave in their raw form. I have 2 micro switches, 1 push button, and 1 toggle switch:Īll the switches will be connected the same way (this is essential if we are going to compare the results). I will show you how 4 different switches bounce. If you compare two of the same switches, there is a great chance that they will bounce differently. The following screenshots illustrates a typical switch bounce, without any sort of bounce control:Įach switch has its own characteristics regarding the bounce. The hardware is often an integrated circuit. 'When the switch is closed, the two contacts actually separate and reconnect, typically 10 to 100 times over a periode of about 1ms.' ('The Art of electronics', Horowitz & Hill, Second edition, pg 506.) Usually, the hardware works faster than the bouncing, which results in that the hardware thinks you are pressing the switch several times. The switch is bouncing between in-contact, and not in-contact. Then it makes contact a little longer, and then again a little longer. When you push the switch, it initially makes contact with the other metal part, but just in a brief split of a microsecond. Inside the switch there are moving parts. For the user, it might seem that the contact is made instantly. What is switch bounce? When you push a button, press a mico switch or flip a toggleswitch, two metal parts come together.

First I will take you through the theory, and later I will show you some ways to handle it in both hardware and in software. In this article I will discuss what switch bounce is and some ways to deal with it.
