The **M2SES2-63-R** is a specific part number typically associated with **M2 Series Rotary Selector Switches** manufactured by companies like **Altech Corp** or similar industrial control component providers. These components are designed for industrial control panels where a user must manually toggle between different electrical states (e.g., Hand/Off/Auto). --- ### 1. Key Technical Specifications Based on the standard nomenclature for this series, here are the electronic and mechanical characteristics: | Property | Description | | :--- | :--- | | **Component Type** | Rotary Selector Switch (Non-Illuminated) | | **Positions** | 2-Position (Usually 0 and 1 or On/Off) | | **Rotation Angle** | 90° | | **Operation Mode** | Stay-put (Maintained) — it stays in the position you turn it to. | | **Bezel Material** | Plastic (indicated by the 'M2' series prefix) | | **Color** | Black (indicated by 'R' or standard series codes) | | **Mounting Diameter** | 22.5 mm (Standard industrial cutout) | --- ### 2. Functional Breakdown #### Mechanical Build The unit consists of the **Actuator** (the knob you turn) and is designed to be snapped onto a **Contact Block Carrier**. The "63" in the part number often refers to a specific knob style or handle length within the manufacturer's catalog. #### Contact Blocks While the part number refers to the *actuator*, its electronic function is determined by the contact blocks attached to the back: * **NO (Normally Open):** Completes the circuit when the switch is turned. * **NC (Normally Closed):** Breaks the circuit when the switch is turned. #### Environmental Ratings These parts are built for harsh environments and typically carry the following ratings: * **IP65/IP67:** Protection against dust and water jets. * **NEMA 4/4X/12:** Suitable for indoor and outdoor industrial use, often resistant to corrosion. --- ### 3. Application Example In an industrial control circuit, the M2SES2-63-R acts as the human-machine interface (HMI). ```yaml Circuit Example: - Input: 24V DC / 120V AC Control Power - Switch: M2SES2-63-R (with 1 NO Contact Block) - Load: Motor Starter Coil - Action: When turned to position 1, the NO contact closes, energizing the coil and starting the motor. ``` --- ### 4. Mounting & Installation 1. Insert the actuator through a **22.5mm** hole in the panel. 2. Tighten the locking nut from the rear. 3. Snap the contact block adapter onto the back of the actuator. 4. Wire the control lines into the screw terminals of the contact blocks.
