Characteristics of the Product

cz141%e5%85%a8%e4%bd%933Our precisely-designed small size switch makes the operability-driven designing be compatible with superior functions.
All our switches satisfy the protection level of IP67 class for resistance to both water and dust. We pride ourselves on our products that are highly durable in any operational environment.
Here at Asahi Denso, with a successful casting of previously-nonexistent large resin parts, we succeeded in producing a lever integrated into an armrest.
We adopted the material which satisfies both durability and design that gives agricultures dreams and makes farmers proud.
