What is a rubber button?

A silicone rubber keypad, also known as an elastomeric keypad, is a type of keypad that’s designed using webbing material consisting of silicone rubber around a center switch. Each key, for example, features silicone rubber webbing around a switch.

What is snap ratio?

Snap ratio refers to the level of tactile feedback produced by a keypad, including silicone rubber keypads. The higher the snap ratio, the greater the tactile feedback. Although there are exceptions, most silicone rubber keypads produce at least some tactile feedback.

How do you make conductive silicone rubber?

A typical first mix would be 3/4 teaspoon of graphite to 1/16 teaspoon corn starch to 1/4 teaspoon silicone caulk. First mix the graphite and corn starch together with enough Naphtha to make a thick paste of the powders. Then add the silicone caulk and mix it very well with a Popsicle stick or stirring rod.

How are the buttons on a remote control made?

The buttons themselves are made of a thin rubbery sheet. For each button there is a black conductive disk. When the disk touches the contacts on the printed circuit board, it connects them and the chip can sense that connection.

What kind of material is a remote control made out of?

There are several methods used to create the tactile feedback including the use of metal domes placed inside the dome area. Domed membrane switches are low profile. Adhesive is used to ensure the membrane keypad adheres to the face of the remote control. Membrane keys are typically made from PET, a Polyethylene material or PC, Polycarbonate.

Why are silicone rubber buttons made of silicone?

These polymers are used in production of silicone rubber, silicone resign, silicone grease and silicone oil. Silicones possess several extremely useful properties that give them clear advantage over the other materials used for the same purposes.

Why are silicone rubber buttons used for keypads?

Silicone rubber buttons are resilient to many external forces, provide tactile feedback, and can be printed on and numerous other features. One of the most common features of silicone rubber keypads is molding a carbon contact pill on the backside. The carbon contact pill will complete a circuit on a PCB when the silicone rubber is pressed.
