Height 1.0 mm, body area reduced by 44% compared to existing products (SOE series)
Thin tactile button switch
SOF series
Announced on May 8, 2009
Overview
In response to the requirements for smaller, thinner electronic devices, we have developed the <SOF series> which offers a reduction in mounting surface area and substantially lower profile.
The <SOF series> does not sacrifice feel, lifetime or ease of mounting, and provides the same high usability as antecedents.
Due to the smaller size and thickness, an expansion of share and increase in demand is expected in the cell phone handset market.

§ Features
1.
Extreme low profile (body portion/button portion height is 1 mm) and small mounting area (2.9 ~ 3.3 mm).
2.
Earth and signal terminals have the same structure. This prevents flux lifting and improves terminal coplanarity.
3.
Connections are film-sealed, improving dust protection and environment resistance.
