The failure rate is 1/20 of that of air contacts! A long-lasting micro switch!
Micro switch PPUU type
Direct switching is possible even with devices that have high time constants for inductive loads! The PPUU type micro switch boasts low failure rates, outstanding reliability, and long lifespan.
Our PPUU type micro switch has a wide control load range from low-level signal circuits to power circuits, and it offers high contact reliability even with infrequent to frequent use. Due to this high reliability, it is also favored for use in master controller switches and door open/close detection switches in railway vehicles. This product features our proprietary power lead switch "Bestact," which is built-in, and products with this "Bestact" have been proven to have high reliability in various usage environments compared to other manufacturers' products. 【Product Features】*Comparison with equivalent products from other manufacturers ○ "High contact reliability": Low failure rate and long lifespan due to unique contact mechanism ○ "Strong environmental resistance": Minimal long-term deterioration from external environments and strong against high temperatures and humidity ○ "High vibration and shock resistance": Strong against vibration and shock due to unique contact mechanism ○ "Compatible with small to large capacities": Operates with high contact reliability from small to large capacities ○ "Low maintenance frequency": Long lifespan reduces maintenance burden Customers looking for micro switches are welcome to consult with us.

Company information
For over 40 years, our relays and sensors have been trusted and used in various markets where reliability and safety are essential, such as in Shinkansen (bullet trains) and steel manufacturing. With advantages such as an electrical lifespan that is twice that of standard relays and a failure rate of 1/20 under low loads, we contribute to improving equipment reliability while also reducing running costs by decreasing the frequency of replacements. Leveraging the excellent environmental resistance of our products, they perform well even in harsh conditions, such as in vegetable factories where humidity is present.
