The **L2CA-53-R** is a specific part number belonging to the **NKK Switches** CWS series. It is a sub-miniature, high-capacity rocker switch designed for power circuit applications where space is limited. --- ### 1. Key Technical Specifications The following table summarizes the primary electrical and mechanical characteristics of the L2CA-53-R: | Parameter | Specification | | :--- | :--- | | **Switch Function** | SPST (Single Pole Single Throw) | | **Circuit Arrangement** | ON - OFF | | **Current Rating** | 6A @ 250V AC | | **Voltage Rating** | 250V AC | | **Termination Style** | .187" (4.75mm) Quick Connect / Tab | | **Actuator Type** | Rocker (Curved) | | **Color** | Red (Actuator) / Black (Housing) | | **Contact Material** | Silver Alloy | --- ### 2. Internal Components & Materials The electronic and structural integrity of the switch is defined by its internal composition: * **Contacts:** Uses silver alloy contacts to ensure high conductivity and to resist "pitting" or welding during high-current switching. * **Case/Housing:** Typically constructed from **Polyamide (Nylon)** or a similar heat-resistant thermoplastic, ensuring it can withstand internal heat generated by 6A loads. * **Actuator:** The red rocker is made from Polycarbonate or Polyamide, often featuring a smooth finish for tactile comfort. * **Terminal Pins:** Brass with silver plating to facilitate easy soldering or secure connection with quick-connect crimp terminals. --- ### 3. Electronic Application & Usage The L2CA-53-R is categorized as a "High Capacity" switch despite its small footprint. It is commonly found in: 1. **Power Supplies:** Used as a primary power toggle for small desktop or bench-top electronics. 2. **Consumer Appliances:** Integrated into small kitchen appliances or handheld tools. 3. **Industrial Controls:** Used in control panels where a clear visual indicator (Red) and high AC current handling are required. 4. **Audio/Video Equipment:** Found on the rear panels of amplifiers or studio gear. ### 4. Mounting & Physical Dimensions The device is designed for **Snap-In** mounting, meaning no screws are required to secure it to a panel. * **Panel Cutout:** Rectangular (standard sub-miniature size). * **Orientation:** The switch is polarized via the physical orientation of the tab terminals on the underside. ---
