Pushbuttons are the simplest and most common form of control.
Microswitch Pushbuttons
Pushbuttons come is various forms and shapes, though the most common is the Industrias Lorenzo (iL) horizontal microswitch pushbutton (aka Happ Horizontal Pushbutton). Due to the microswitch, these buttons have a 'clicky' activation that can seem a little alien to many old-school gamers. They are comprised of...
- Button plunger
- Button housing/bezel
- Spring
- Microswitch
The plunger top may be concave, flat, or convex. The microswitch can be orientated horizontally or vertically. Most people prefer horizontal orientation as these tend to be more reliable (read why here.) Microswitch pushbuttons are probably the most popular type of button using in arcade. Because of this they can be found in almost any color, including transparent. These also can be found with little men icons, generally used as start buttons for the player indicated.
These buttons are sold by numerous vendors. Common suppliers are Happ, Ultimarc, FX Buttons and GroovyGameGear.
Installation requires a 1 1/8" hole.
Leafswitch Pushbuttons
Before microswitch pushbuttons appeared, leafswitch pushbuttons were the de facto standards and are still prefered by many people today. The main advantage to leafswitches over microswitched is that they're almost completely silent. They are comprised of...
- Button
- Button holder (usually with the actual leafswitch attached)
- Pal nut
As with most types of pushbuttons, they come in two lengths; long (1 7/8") for wooden panels and short (1 5/8") for metal panels.
It is occasionally difficult to find buttons of the appropriate color and the appropriate length for a particular project. In those situations, check Leaf Switches & Button Solutions by The Real Bob Roberts for potential solutions.

Also known as cone buttons, volcano buttons are comprised of:
- Microswitch
- Lens (plunger)
- Plastic mounting clip/brace
- Plastic or aluminium cone
These were used as player start buttons in many Atari cabinets, available with illuminated red and later solid black lenses. The red button lens would blink when a player inserted a coin and remain lit during gameplay. Taller cones were used on fire buttons of Missile Command.
The actual switch used appears to be a Cherry DB3 sub-miniature microswitch. This switch is still available from Cherry, however the plastic mounting clip and lenses have been out of production for some time. The plastic cones have been re-produced by Gamecab, but are currently unnavailable.
Charlie from Gamecab.com discovered that a company called EAO currently manufacures switch assemblies that are quite similar to the original Cherry P163 assemblies. They don't include an LED, but the neck is threaded the same as an Atari cone, so they work pretty well together. They are available from Newark In One.
