Downsize machines
with the world's smallest switches

The world's smallest M5 x 17 mm Precision positioning switches. Used for origin detection in various industrial machines and medical machines such as CNC machine tools, semiconductor production equipments, microscopes for neurosurgery and disc brakes.

1μm repeatability,  3million contact life time

1μm repeatability,
3million contact life time

The precision positioning switch using no amp does not cause signal point drift due to external environment or self-generation and can output stable high precision signals. This ultra small switches endure 3 million times operation mechanically and electrically.

0.001mm repeatability has been proven by painstaking testing

Applications

The Pride of Japan Technology

Little Big Heros behind manufacturing.

[History of Development]
The world's smallest Positioning Switches

Ultra Small Size Positioning Switches [PT] are small heros who secretly support manufacturing all over the world by "precision positioning".

The first idea for PT-Touch Switches dates back to 2006.
Large-scale semiconductor device manufacturers called saying,
"The compact switches we currently use are problematic as they often break.
I want a tough yet compact and highly accurate switch..."
