Alps Alpine has launched the SPVQK Series, an automotive detector switch designed to support the growing adoption of 48V electrical architectures in next-generation EVs. The product reportedly ensures reliable switching performance under demanding electrical conditions and simplifies circuit design.
With a maximum rated voltage of 52V DC, the SPVQK Series can be used directly in 48V electrical systems without requiring voltage conversion circuitry.
The SPVQK Series withstands up to 3A peak (C-load), providing significantly greater robustness during switching. Its newly developed contact structure minimizes contact wear and degradation, ensuring stable electrical performance and long-term reliability. In addition, external current-limiting components, such as chip resistors previously required for circuit protection, are no longer necessary.
According to Alps Alpine, the switch delivers the high reliability required for automotive applications, withstanding overcurrent of up to 18A for five minutes (typical value) and providing an operational life of 300,000 cycles. Its dust- and water-resistant construction, compliant with IP6K7, ensures stable performance even in harsh operating environments.
The product shares the same form factor as the previous SPVQ8 Series, allowing adoption with minimal design changes and supporting a straightforward transition from existing products. It is designed for automotive applications including door latches, seatbelt buckles, electric parking brakes (EPBs) and column shifters, as well as consumer electronics such as smart locks and home appliances.
