Product history

[[ Behind-the-scene story of the development. ]]

Although we are a supplier that does not belong to any car manufacturer's group and we entered the power window switch market late, in 1989 we came up with the revolutionary "built-in switch concept" that was the first in the industry. This concept was completely new, as switches were previously made of molded resin and metal, but instead were made by mounting a small built-in switch on a board.
At that time in the automotive industry, a supply chain was established in which switches were sourced from switch suppliers that belonged to the group, but it was no easy feat for a completely unknown supplier outside the group to make inroads. That is how big an impact the new concept proposed by our company had in terms of quality and cost. After that, we incorporated many groundbreaking technologies, such as incorporating a snap action mechanism in the built-in switch to enable further miniaturization of the switch and a fail-safe structure to prevent smoke and fire, and evolved it into a long-lasting, highly reliable and safe, yet inexpensive product that was adopted by almost all Japanese car manufacturers.
Even after entering the market, we continue to focus on establishing differentiating technologies that keep us one step ahead of our competitors. Our track record of development to date includes entrapment prevention technology that reverses the window glass when a finger or arm gets caught in the window, submersion detection technology that allows the window glass to be lowered for a certain period of time even if a vehicle falls into the sea or river and people are trapped inside the vehicle, and ripple control technology that enables simultaneous control of multiple windows to inexpensively add entrapment prevention functionality to the four seats that are essential to preventing children from getting caught in the windows in the back seats.
In the future, we will continue to contribute to the realization of safety and security for end users by proactively proposing solutions to problems and commercializing them ahead of our competitors in response to the increasing safety needs of the world.
