These switches offer twice the functionality in half the size, meeting the growing demand for miniaturized yet dependable components.
Panasonic Industry has launched its latest ASQD1 series of seal-type sliding switches—precision-engineered micro switches built to meet modern needs for space-saving design, high reliability, and safety-critical functionality. These next-gen switches are ideal for industries demanding consistent performance, failure detection, and compact integration.
A key innovation in the series lies in its dual internal circuit structure, which unlocks multiple application possibilities: from redundancy and failure detection to two-step detection—all within a compact, sealed body. This flexible circuit design enables engineers to reduce the number of components, simplify wiring, and streamline assembly.
The lineup includes three variants tailored to specific needs:
- Two-Step Detection Type: This version allows detection of two mechanical positions using just one switch—making it perfect for latch or door closure applications. It can detect both the “pre-close” and “full-close” stages, saving space and cutting component cost, while simplifying tolerance management in the design phase.
- Redundancy Type: Featuring two circuits within a single, small-form factor housing, this is Panasonic’s first-ever 3-terminal micro switch with built-in redundancy. It ensures functionality continues even if one circuit fails, delivering critical safety assurance for mission-critical operations.
- Failure Detection Type: Designed with functional safety in mind, this variant actively detects internal circuit or wiring failures. It can immediately notify the system about the nature of the fault, making it essential in applications where safety diagnostics are mandatory.
In addition to their advanced circuit capabilities, all ASQD1 switches come with IP67 protection, silent operation, high contact reliability, long stroke, and superior resistance to shock and vibration—making them robust enough for harsh environments.
