The **M2SES-2BA-R/CE** is a specific model within the industrial automation and control component category, typically manufactured by brands like **IDEC** or similar industrial hardware providers. It belongs to the **M2** series of miniature selector switches. --- ### 1. General Specifications This part is a **Key Selector Switch**, designed for secure industrial panel mounting where only authorized personnel with a key can change the device state. | Feature | Specification | | :--- | :--- | | **Series** | M2 Series (Miniature Control Units) | | **Type** | Key Selector Switch | | **Mounting Hole** | 22mm (Standard industrial size) | | **Shape** | Round Bezel | | **Operation** | 2-Position, Maintained (Stay-put) | | **Contact Configuration** | 2NO (Two Normally Open contacts) | | **Key Removal** | Key removable in both Left and Right positions | --- ### 2. Electronic & Mechanical Breakdown The part number can be decoded into specific functional attributes: #### A. Contact Block (2BA) * **2**: Indicates two contact blocks are included. * **BA**: Refers to the contact type, usually **Normally Open (NO)** silver contacts. * **Voltage/Current Rating**: Typically rated for **10A** at **120V AC** or **5A** at **240V AC** (Resistive load). #### B. Operator Style (R/CE) * **R**: Denotes a **Round** bezel/shape. * **CE**: Confirms compliance with European safety standards (**Conformité Européenne**), ensuring it meets low voltage and electromagnetic compatibility directives. #### C. Switching Logic As a **Maintained 2-Position** switch, the internal contacts behave as follows: * **Position 1 (Left):** Contacts are open (Circuit broken). * **Position 2 (Right):** Contacts are closed (Circuit completed). * The switch stays in the last position set; it does not spring back to center. --- ### 3. Application Use Cases Because this is a **Key-operated** device, it is used in scenarios where safety and security are paramount: 1. **Machine Enable/Disable:** Preventing unauthorized startup of heavy machinery. 2. **Mode Selection:** Switching between "Manual" and "Automatic" modes in a PLC-controlled system. 3. **Override Switches:** Bypassing security sensors for maintenance purposes. 4. **Control Panels:** Standard 22mm cutout makes it compatible with most industrial enclosures. --- ### 4.
