# Industrial Specification: Emergency Stop Button

## 1. Technical Definition
A safety-critical push-button device designed to immediately halt machinery or processes when activated.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.0 N actuation force, -25°C to +70°C ambient temperature, 24V DC ±10% or 110-480V AC ±15% supply voltage**. Failure boundary: **Contact resistance exceeding 50 mΩ, insulation resistance below 100 MΩ at 500V DC, mechanical life &lt;100,000 actuations**, Mechanism: **Contact welding due to inrush currents exceeding 10A, polymer degradation from UV exposure at &gt;75 kJ/m² cumulative dose, spring fatigue at &gt;10⁷ stress cycles**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Contact contamination by conductive particles &gt;50 µm | 8 | Contact bridging causing false activation or failure to de-energize | IP67-rated sealed enclosure with 0.5 µm particle filtration |
| Plasticizer migration from PVC insulation at &gt;60°C | 8 | Button sticking in depressed position due to increased static friction &gt;1.5 N | Silicone-free thermoplastic elastomer with glass transition temperature &gt;120°C |

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are used in this emergency stop button for durability?
**A**: The button features a thermoset plastic cap for impact resistance, a metal alloy housing/actuator for structural integrity, and copper alloy electrical contacts for reliable conductivity and corrosion resistance.

### Q: How does the emergency stop button ensure immediate machinery shutdown?
**A**: When activated, the actuator mechanism instantly breaks the electrical circuit via the contact block, sending a stop signal to the machinery control system to halt all operations immediately.

### Q: What components are included in the BOM for installation?
**A**: The bill of materials includes the actuator mechanism, button cap, contact block, and mounting ring/bezel for secure panel installation in machinery and equipment.

## 6. Manufacturing Compliance
- ISO 13850:2015 - SAFETY OF MACHINERY - EMERGENCY STOP FUNCTION - PRINCIPLES FOR DESIGN
