The **F1SP-R10-JB** is an industrial-grade **Single-Pole Single-Throw (SPST) Pushbutton Switch** manufactured by **IDEC** (part of the FB series). It is primarily used in control panels, emergency stop stations, and automation interfaces. --- ## 1. Technical Specifications The core electronic and physical attributes of the F1SP-R10-JB are summarized below: | Feature | Specification | | :--- | :--- | | **Contact Configuration** | 1NO (Normally Open) | | **Switch Operation** | Momentary (Non-locking) | | **Current Rating** | 10A (Thermal) | | **Voltage Rating** | 600V AC/DC max | | **Terminal Type** | Screw Terminals (M3.5) | | **Mounting Hole Size** | 22mm / 30mm (depending on adapter) | | **Contact Material** | Silver-based contacts | --- ## 2. Key Electronic Components ### A. Contact Block (R10) The "R10" suffix indicates the contact block configuration. In this case, it features **1 Normally Open (1NO)** contact. When the button is pressed, the internal metallic bridge completes the circuit, allowing current to flow. ### B. Self-Cleaning Contacts The internal electronic contacts are designed with a "rolling" or "sliding" action. Each time the switch is toggled, the friction removes small amounts of oxidation or dust, ensuring low electrical resistance over thousands of cycles. ### C. Insulation Resistance The unit is built with high-grade polycarbonate housing to provide an insulation resistance of **100 MΩ minimum** (500V DC megger), preventing leakage current between the terminals and the panel frame. --- ## 3. Physical & Environmental Attributes While the electronics handle the signal, the housing ensures the electronics remain functional in harsh environments: * **Ingress Protection:** Typically rated **IP65**, protecting the internal electrical contacts from dust and water jets. * **Mechanical Durability:** Rated for over 5,000,000 operations. * **Shock/Vibration Resistance:** Designed to withstand industrial machinery vibrations without causing "contact bounce" (unintended signaling). --- ## 4. Typical Applications 1. **PLC Inputs:** Sending a start/stop pulse to a Programmable Logic Controller. 2. **Motor Starters:** Acting as the "Start" button in a magnetic starter circuit. 3. **Relay Logic:** Direct control of small relays or contactors.
