Micro switch has a failure rate that is 1/20 of that of air contacts and has a long lifespan.
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, exceptional 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 widely used in railway vehicle master controller switches and door open/close detection switches. 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 under various usage environments compared to competitors' products. 【Product Features】*Comparison with equivalent products from other companies ○ "High contact reliability": Low failure rate and long lifespan due to unique contact mechanism ○ "Strong environmental resistance": Minimal long-term degradation 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 Details about Bestact are explained on our website's "What is Bestact" page.

Company information
For over 40 years, our relays and sensors have been used in various markets where reliability and safety are required, such as in Shinkansen (bullet trains) and steel manufacturing. With advantages such as an electrical lifespan that is twice that of general relays and a failure rate that is 1/20 under minimal loads, our products 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 environments, such as in vegetable factories where humidity is present.
