High-Performance original Ultimarc Pushbuttons with integral minature gold-plated leaf switches.
Available in Red, Blue, Green, Yellow, Black, Orange, White and Pink.

This is the ultimate button with gold-plated leaf switches, perfect for every arcade machine.
But also ideal for (virtual) pinball machines, with this button: no separate leaf switch, no separate pal nut and no separate flipper button, as this button is an "all-in-one" solution!

FEATURES:
Gold-plated contacts.    No tarnishing nor degradation results in no deterioration in response. The contact leaves and the external connections are fully gold plated.
Low inertia.    The moving part of the button is ultra-light and only 10mm deep, unlike other types where the plunger extends the full depth of the button.
No Click.    Leaf switch means no clicking micro-switch.
No Plunger Spring.    The body of the button contains no large spring. This results in a uniquely low actuation force of 45 grams for the entire button.
No Hysteresis. This is the difference in button depression for the contact close and open points. On these buttons the position is the same, resulting in maximum repeated actuation performance. On micro-switch buttons this "dead" distance can be up to 1.5 mm.
Concave top. Most serious gamers prefer the classic concave tops over the convex which are commonly used on Japanese low-inertia buttons.
Robust.    The limit stop of the button is supported by the button body not the switch so no chance of switch damage owing to over-enthusiastic play!
Compact integral design.    No fiddly assembly after fitting through the panel. Totally enclosed leaf-switch contacts.
Economic.    Despite their performance these are similar in price to standard arcade buttons and the price is all-inclusive, nothing extra to pay for add-on switch options.
Nut & Thread Fixing.  We have retained the traditional threaded fixing rather than the push-in design of certain other low-inertia buttons as we believe this gives the most effective permanent mounting in all types of panel up to 19mm (3/4 in).

These pushbuttons have 2.8mm connector tags. 
For Mini-PAC pre-made harnesses, select the 4.7mm types, these fit satisfactorily.

Diameter for mounting hole: 28~30mm
Diameter bezel (top): 33,60mm
Depth (from bottom bezel to bottom barrel): 34mm
