The part number **M2PHS2L-BA-R/CE** refers to a high-quality industrial **Push Button Switch**, typically manufactured by companies like **IDEC** or **IDEC-Izumi** (part of their M2 series). These components are designed for control panels, pilot devices, and human-machine interface (HMI) systems. --- ### 1. Technical Specifications Breakdowns The alphanumeric string defines the physical and electrical characteristics of the switch: | Parameter | Specification | |:---|:---| | **Series** | M2 Series (Small-sized/Compact) | | **Mounting Hole** | 16mm (Typical for M2 series) | | **Operator Type** | Round, Extended (L-BA-R) | | **Contact Configuration** | Likely DPDT (Double Pole Double Throw) or SPDT | | **Illumination** | Non-Illuminated (standard for /CE suffix) | | **Action** | Momentary (Spring return) | | **Terminal Type** | Solder/Tab terminals | | **Compliance** | CE (European Conformity) marked | --- ### 2. Core Electronic Components A switch of this type consists of three primary internal sub-assemblies: #### A. The Contact Block This is the electrical heart of the device. It utilizes a **snap-action mechanism** that ensures rapid transition between the "Normally Open" (NO) and "Normally Closed" (NC) states, minimizing electrical arcing and extending the life of the silver-plated contacts. #### B. The Operator (Actuator) The **"L-BA-R"** portion of the code signifies: * **L:** Large or Extended button style. * **BA:** Bezel/Body configuration. * **R:** Red color button head. #### C. The Housing Constructed from flame-retardant polymers (V-0 rating), the housing provides insulation and mechanical stability, ensuring the device can withstand industrial environments and high-frequency usage. --- ### 3. Electrical Ratings While specific tolerances can vary slightly by regional production, the M2 series generally follows these parameters: * **Rated Insulation Voltage (Ui):** 250V AC/DC. * **Thermal Current (Ith):** 3A to 5A. * **Operational Voltage/Current:** * 125V AC @ 3A * 250V AC @ 2A * 30V DC @ 2A * **Contact Resistance:** 50 mΩ maximum (initial). * **Mechanical Life:** Over 1,000,000 operations. --- ### 4. Common Applications * **Industrial Control Panels:** Used as "Stop" or "Reset" buttons. * **Medical Equipment:** Compact size allows for dense array mounting. * **Telecommunications:** Signal routing and power switching for peripheral devices. * **Laboratory Instruments:** Precise tactile feedback for user inputs.
