The **F2TS-23-R/K** is a specific model of an industrial-grade **Foot Switch** (often referred to as a pedal switch). These components are primarily used in industrial automation, medical equipment, and heavy machinery to provide hands-free control over electrical circuits. Below is a breakdown of its electronic and mechanical specifications: --- ### 1. Technical Specifications | Feature | Specification | | :--- | :--- | | **Contact Configuration** | 1c (SPDT - Single Pole Double Throw) | | **Rated Voltage/Current** | 10A 250VAC (Standard heavy-duty rating) | | **Insulation Resistance** | 100MΩ min. (at 500VDC) | | **Dielectric Strength** | 2,000VAC for 1 minute | | **Mechanical Life** | 1,000,000 operations min. | | **Electrical Life** | 100,000 operations min. | | **Operating Temperature** | -10°C to +70°C | --- ### 2. Electronic Parts & Internal Mechanics The F2TS-23-R/K consists of several key sub-components that ensure reliable electronic switching: * **Micro Switch Core:** The heart of the pedal is a high-quality micro switch. When the pedal is pressed, it physically triggers the plunger of the micro switch to flip the internal contact from the **Normally Closed (NC)** position to the **Normally Open (NO)** position. * **Terminal Block:** Located inside the casing, it usually features screw terminals for easy wiring. The "R/K" designation often refers to specific wiring configurations or cable gland entry types. * **Return Spring:** A heavy-duty steel spring that ensures the circuit returns to its default state (OFF) as soon as the operator lifts their foot. * **Built-in Cable Gland:** Ensures the electrical connection is strain-relieved and protected against dust and moisture ingress. --- ### 3. Suffix Meaning (R/K) In many industrial parts numbering systems (like those used by manufacturers such as *KACON* or *Tend*), the suffixes represent specific variations: * **R:** Usually indicates a **Red** pedal color or a specific Reset function. * **K:** Often indicates a **Guard Cover** (Safety Cover) is included. The cover prevents accidental activation if a tool is dropped on the switch. --- ### 4. Circuit Diagram Logic The switch functions as a standard **SPDT** (Single Pole Double Throw) device: ```text [COM] (Common) | ----------- | | [NC] [NO] (Closed) (Open) ``` 1. **Idle State:** Current flows from `COM` to `NC`. 2. **Pressed State:** The connection flips; current flows from `COM` to `NO`. ---
