Operating force: The amount of gram force required to hit the actuation point.
When shown without a graph it can be displayed in several ways: This is typically displayed in a graph with Y axis being the gram force and X axis the travel distance in millimeter (mm). When you press the switch, you need to apply a certain amount of gram force to press it down. The latter is commonly referred to as Linear switches. Audible feedback is typically a metal click sound, tactile feedback is in the form of a slight bump in the press, and none has no feedback at all. There are 3 types: Audible, Tactile, or None. When the key reaches its actuation point you’ll receive audible or tactile feedback from the switch. A typical mechanical keyboard switch has a reset point near the actuation point, around 1.8mm. Just like an actuation point, it’s expressed in a position over the switch travel distance. The moment a key is registered as deactivated is your reset point. A typical mechanical keyboard switch has an actuation point set at 2mm. This is usually expressed in a position over the switch travel distance. The moment a key is registered as activated is your actuation point.
This can be as low as 1mm with scissor switches. A typical mechanical keyboard switch has a 4mm travel distance. Depending on the magnet’s proximity to the sensor, it activates the key.Įvery mechanical keyboard switch has a travel distance expressed in millimeters (mm). These are available in many types with different characteristics but the same technology.Īn uncommon technology is the Hall effect switch, a magnet inside the switch is measured by a magnet sensor on the keyboard. The most common technology is a leaf switch, this is the simple act of connecting 2 copper leaves to activate the key. That’s why there are multiple types of switches with the same or different technology. The digital function of a switch, active or non-active, is very simple. When a key is active, it’ll send data to the computer, registering your press until the key is deactivated. All switches have one purpose, to activate or deactivate a key.
