The **A101P3CWCQ0Q** is a specific model of a sub-miniature toggle switch manufactured by TE Connectivity (specifically under the ALCOSWITCH brand). This part is designed for high reliability and panel mounting in electronic circuits. --- ### ## Technical Specifications The following table outlines the primary electrical and mechanical characteristics of the device: | Feature | Specification | | :--- | :--- | | **Manufacturer** | TE Connectivity / Alcoswitch | | **Switch Configuration** | SPDT (Single Pole Double Throw) | | **Switch Function** | ON-NONE-ON | | **Contact Rating** | 5A @ 120VAC or 28VDC; 2A @ 250VAC | | **Termination Style** | PC Pin (Through-hole) | | **Actuator Style** | Flatted Lever (P3 style) | | **Bushing Type** | 1/4-40 Threaded (CW - Splashproof) | | **Contact Plating** | Silver (Q) | --- ### ### Key Components & Materials 1. **Actuator (P3):** The "P3" designation refers to a flatted toggle lever. This provides a ergonomic grip and a distinct visual orientation compared to standard round bat toggles. 2. **Bushing (CW):** This indicates a "Splashproof" bushing. It typically includes an internal O-ring seal to prevent liquids or dust from entering the switch body through the actuator hole. 3. **Contacts (Q):** The "Q" suffix denotes **Silver contacts**. Silver is excellent for power switching applications but can tarnish over time if used in very low-current (logic level) applications without enough voltage to "wipe" the oxidation. 4. **Housing:** Usually made of diallyl phthalate (DAP), a high-strength plastic with excellent electrical insulation and heat resistance for soldering. --- ### ### Circuit Diagram (SPDT) The SPDT (Single Pole Double Throw) configuration means there is one common terminal that can be connected to one of two other terminals. ```text [1] (Output A) / [2]--o (Common) \ [3] (Output B) ``` * **Position 1:** Terminal 2 is connected to Terminal 3. * **Position 2:** Terminal 2 is connected to Terminal 1. --- ### ### Typical Applications * **Industrial Control Panels:** Due to the splashproof rating. * **Instrumentation:** Used for mode selection or power toggling. * **Medical Equipment:** High reliability and tactile feedback. * **Audio/Visual Gear:** Signal routing or power switching. ---
