Key Features Operator Type: Key‑operated selector switch with removable key. Positions & Action: 2‑position maintained action — remains in the selected position until changed manually. Contacts: Integrated 2 normally open (NO) + 2 normally closed (NC) contacts, enabling multiple circuit switching functions. Actuator: Key‑activated rotary selector (provides secure control and prevents accidental actuation). Construction: Modular plastic housing suited for industrial control panel mounting. Front Protection: High ingress protection on the front panel when installed (dust and water resistance). Terminal Connections: Screw‑type terminals for secure wiring. Electrical Ratings Rated Control Voltage: Suitable for typical industrial control voltages (AC/DC supply). Rated Insulation Voltage: Designed for low‑voltage control circuits (up to ~690 V). Contact Rating: Suitable for AC and DC control loads within typical pilot device ratings. Functional control of relays, PLC inputs, contactors, and indicator circuits. Mechanical & Environmental Mounting: Standard 22 mm panel cut‑out for pilot devices. Mechanical Durability: Designed for a high number of operation cycles in control panel environments. Operating Temperature Range: Suitable for typical industrial ambient conditions (approx. –25 °C to +70 °C). Storage Temperature Range: Broader range for transport and storage. Front Protection Rating: High degree of dust and water resistance when mounted properly; terminals are protected when enclosed. Physical & Installation Dimensions: Fits standard 22 mm panel hole and aligns with modular pilot device layouts. Bezel / Housing: Durable plastic construction for rugged installation. Key: Removable key provides security and can be configured to be removed in one or both positions by variant. Typical Applications Control panel selector for mode or function control (e.g., Off/On, Manual/Auto). Secure operator interface where key‑only access is needed. PLC or relay control inputs requiring two distinct switch states. Machine and automation systems where human intervention is controlled by key operation.
