More advanced compact and good touch feeling switches
With button compact tactile switches
SOF series
Announced on September 19, 2008
Overview
We have developed the push switch that has the button on its top and of which the thickness is 1mm, and in this development the base of the thin side click type tactile switches that are presently in the commercial production is utilized while replacing their button and cover on the top with new ones. The thickness of the push switch itself is 1mm.
In these new products, as compared to our current products (SOE series products), the thickness and packaging footprint are reduced by 33% and 25% respectively, which will be beneficial and effective to make the portable equipment smaller. In addition, there are two types of the model, the thickness of which is different to allow you to select one of the two types that satisfies your needs.

§ Features
1.
External dimensions : 3.3Χ2.9mm (Thickness of the switch itself is 1mm, whereas the button is 1.2mm or 1.5mm in height.)
2.
Contacts are covered with tape to provide superior dust proofing and weather proofing.
3.
Good touch feeling and longer switch life are achieved thanks to the stainless steel click spring.
4.
Good mechanism to make it possible to push right on the sweet spot on the switch by ingeniously designing the click spring and button shape.
