The **22LA1-3C7-R** is a specific model of an industrial **Push Button Switch**, typically manufactured by brands like **DECA SwitchLab**. It is designed for panel mounting in control systems, machinery, and automation interfaces. --- ### ## Technical Specifications Below are the primary electronic and physical characteristics of the 22LA1-3C7-R: | Feature | Specification | | :--- | :--- | | **Mounting Diameter** | 22mm (Standard Industrial Size) | | **Action Type** | Alternate / Latching (Push-ON, Push-OFF) | | **Contact Configuration** | 1NO (Normally Open) + 1NC (Normally Closed) | | **Illumination** | Non-Illuminated (standard for this specific suffix) | | **Button Shape** | Round / Flush | | **Color** | Red (indicated by the "-R" suffix) | | **Contact Rating** | Typically 5A @ 250VAC | | **Terminal Type** | Solder / Plug-in Terminals | --- ### ### Component Breakdown 1. **22**: Refers to the **22mm** installation hole diameter. This is the global standard for industrial control panels. 2. **LA1**: The series designation. The "LA" series generally refers to small-size control switches with high reliability. 3. **3C7**: This code defines the internal contact block and the mechanical operation. * **3**: Often denotes the latching (alternate) mechanism. * **C7**: Specifics regarding the contact arrangement (1NO1NC) and terminal layout. 4. **R**: Represents the actuator color. In this case, **Red**. --- ### ### Key Features * **Latching Mechanism:** Unlike a momentary switch (which springs back immediately), this switch stays in its state after being pressed. You must press it again to release it. * **Modular Design:** The switch usually consists of the actuator (the red button), the housing, and the contact block. These can sometimes be separated for easier wiring. * **Durability:** Designed for high-cycle industrial use, often featuring IP40 or IP65 protection ratings (depending on the specific sealing used) to resist dust and moisture. --- ### ### Common Applications * **Machine Start/Stop:** Used as a main toggle for specific machine functions. * **Control Panels:** Standard fitment for PLC (Programmable Logic Controller) inputs. * **Safety Interlocks:** Though not a dedicated "E-Stop," the red latching button is often used for non-critical stop functions.
