# Industrial Specification: Programmable Switch Matrix

## 1. Technical Definition
A configurable electronic switching network that dynamically routes signals between multiple inputs and outputs within a programmable interconnect system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-5 VDC signal voltage, -40°C to +85°C ambient temperature, 0-95% relative humidity (non-condensing)**. Failure boundary: **Signal voltage exceeding 5.5 VDC causes semiconductor junction breakdown, ambient temperature exceeding 125°C initiates thermal runaway in CMOS transistors, relative humidity exceeding 95% initiates electrochemical migration**, Mechanism: **Avalanche breakdown in semiconductor PN junctions at 5.5 VDC, thermal carrier generation exceeding recombination rate at 125°C (Arrhenius equation with Ea=0.7 eV), dendritic growth between conductors at &gt;95% RH due to ionic contamination**.

### 2.1 Analytical Physics Model
Governed by the **Joule Heating & Thermal Resistance**:

> **Primary Equation**: $P = I^2 R = \frac{V^2}{R}$
