Electronic Component Breakdown #### A. Circuitry: DPDT (Double Pole Double Throw) This part features two separate circuits controlled by a single actuator. Each "pole" can switch between two different output paths. This is ideal for controlling two separate functions simultaneously (e.g., turning on a motor and a status light at the same time). #### B. Switching Logic: Maintained (Latching) Unlike a momentary switch (which springs back immediately), this is a **maintained** switch. When you press it, it stays in the down/on position until you press it again to release it. #### C. LED Illumination (-5C-JS) * **-5C:** Represents the Red LED specification. * **-JS:** Refers to the specific silver-colored, rectangular/square cap style with a metallic finish bezel. * The LED is independent of the switch circuit, meaning it can be wired to stay on constantly or only light up when the switch is activated. #### D. Environmental Sealing The "W" in the part number indicates a **waterproof/splashproof** construction. It utilizes an internal o-ring and a silicone rubber seal to achieve an **IP65 rating**, making it suitable for industrial control panels exposed to moisture or dust. --- ### 3. Dimensional Data * **Bushing Diameter:** 16mm (Standard industrial cutout). * **Body Style:** "CW" (Customizable/Compact White body) with a metallic bezel for a flush-to-panel look. ---
