The **W2TS-22B-R2/Q** is a specific model of an **Industrial Pushbutton Switch**, typically belonging to a series of 22mm control components used in automation and electrical panels. --- ### 1. Component Overview This part is an electromechanical interface designed to open or close an electrical circuit manually. It is characterized by its mounting diameter and specific contact configuration. ### 2. Technical Specifications The following table breaks down the technical aspects based on the model nomenclature: | Feature | Specification | Description | | :--- | :--- | :--- | | **Mounting Diameter** | 22mm | Standard industrial cutout size. | | **Operator Type** | Round Flush/Extended | The physical button head. | | **Contact Configuration** | 2NO (2 Normally Open) | Contains two independent sets of NO contacts. | | **Action Type** | Momentary | Returns to original position after being released. | | **Current Rating** | 10A (typically) | Thermal current rating (Ith). | | **Voltage Rating** | 240V - 600V AC | Dependent on insulation and contact block type. | | **Color** | Red (R) | Often used for stop or alert functions. | --- ### 3. Electronic & Mechanical Parts Breakdown #### A. The Operator (The Head) * **Material:** Often made of chrome-plated plastic or metal for durability. * **Environmental Protection:** Usually rated **IP65/IP66**, meaning it is dust-tight and protected against water jets. #### B. The Contact Blocks (The Electrical Logic) The "22B" designation refers to the contact blocks attached to the back of the switch. * **NO (Normally Open):** The circuit is broken until the button is pressed. * **Terminal Type:** Screw terminals are standard for secure industrial wiring. * **Silver Alloy Contacts:** Used to minimize electrical resistance and prevent oxidation over long-term use. #### C. The Mounting Collar * This is the bridge between the operator and the contact blocks. It features a locking mechanism that allows the operator to be installed through the panel while the blocks are snapped on from the rear. --- ### 4. Typical Applications * **Motor Control Centers (MCC):** Starting or stopping motors. * **Control Panels:** Manual override for automated logic. * **PLC Inputs:** Sending a digital signal to a Programmable Logic Controller. ---
