Alps Alpine: Newly developed 1-circuit, 2-contact detection switch SSCZ

As the computerization of automobiles progresses, in addition to being smaller and lighter, the electronic components used are required to have higher precision, as well as to deal with failures, malfunctions, and misoperations. There is a growing need for safety, such as early detection of abnormalities such as disconnection of peripheral circuits.

Even in door lock modules that require small detection switches, there are demands for failure detection functions, improved key lock/unlock accuracy, and improved installation. Based on SSCW, improvements have been made to develop the small detection switch SSCZ.

In recent years, automobiles have been expanding their safety equipment, and the number of vehicles that support automatic locks, such as vehicle speed reaction locks, is increasing. In the automatic locking system, the ECU automatically locks/unlocks depending on the situation, so it is necessary to detect the door lock status.

The existing SSCW (1 circuit, 1 contact) is mainly used to detect vehicle door locks. state can be detected. Furthermore, by adopting a double-sided sliding contact, high contact reliability is ensured even in an environment where shock and vibration are applied. In addition, by changing the internal structure, it has achieved an operating life of 300,000 times, which is three times that of conventional products.

Alps Alpine has been manufacturing and selling automotive detection switches for over 20 years. In addition to the current main application of door open/close detection, the demand for EV charger connection detection and smart rearview mirror on/off detection has increased in recent years, and applications are gradually expanding. I plan to continue.
