Arduino Push Buttons
With the support of an international community of creators, Arduino specialises in the development of easy-to-use hardware and software. The buttons are often connected to Arduino circuit boards, enabling them to control the function of an array of equipment.
2-Position Push Button Switches
These have two set positions for turning the connected device off-on. It is quite common for these switches to be encased in protective plastic, with a key being required for operation.
Dual Push Button Switches
Similar to the two-position variety, dual push button switches feature one button for electrical connection and one for disconnection. The on button is typically green; the off button red. LEDs are another common feature, with the backlighting indicating the status of the device.
Miniature Push Button Switches
Miniature or micro push button switches are available from a variety of brands such as C&K. They are often used for resetting small electronic devices.
Push to Break Switches
Also referred to as normally closed (NC), push to break switches are the most commonly used variety, operating oppositely to latching and momentary types. Electricity can flow to the circuit when no pressure is applied to the button. However, the flow will immediately be broken on pressing. The switch can remain on in either position, with the connection made and broken from separate devices.
Push to Make Switches
The push to make switch enables electricity to flow through the circuit whenever the two contacts are held in. The connection will be broken as the button is released. Common examples include doorbells, calculator buttons, and keyboard keys. Some feature both the push to make and push to break variety, depending on the wiring of the switch.
