FAQ

Q: Do you manufacture waterproof microswitches?
A:Yes,Unionwell, as a micro switch industry leader with more than 20 years of experience, produces waterproof micro switches in addition to push button switches, from IP64 to IP68.

Q: Is the G25-2112U suitable for automotive use?
A: Absolutely! This Unionwell switch is designed for automotive environments, complies with relevant standards (including potential use in ASIL-related functions), and is produced under the strict TS16949 automotive quality management system.

Q: Is the G25-2112U suitable for automotive use?
A: Absolutely! This Unionwell switch is designed for automotive environments, complies with relevant standards (including potential use in ASIL-related functions), and is produced under the strict TS16949 automotive quality management system.

Q: The electrical life (30k cycles) is lower than the mechanical life (300k cycles). Why?
A: This is common. The electrical life rating (30,000 cycles) indicates the switch can reliably make and break its rated electrical load that many times. The much higher mechanical life (300,000 cycles) means the switch's physical mechanism can be pressed and released far more times when switching very low currents (like signal levels) or even with no electrical load at all. It reflects the switch's excellent mechanical durability.

Q: What do RoHS and Reach compliance mean for me?
A: RoHS restricts hazardous substances (like lead, mercury), making the switch safer and more environmentally friendly. Reach addresses chemical substances for human health and environmental protection throughout the supply chain. Compliance ensures the Unionwell G25-2112U meets stringent EU regulations, simplifying your product's path to global markets, especially Europe.
