# Industrial Specification: Joystick/Control Lever

## 1. Technical Definition
A manual input device used to control the movement or operation of machinery through directional manipulation.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-5.0 N·m torque resistance, 0-100 mm displacement, -40°C to 85°C ambient temperature**. Failure boundary: **Potentiometer wiper contact resistance exceeds 10 kΩ, spring return force drops below 0.2 N·m, shaft deflection exceeds 0.5° from neutral position**, Mechanism: **Potentiometer carbon track wear (Archard's wear equation: V = K·W·L/H), spring fatigue (S-N curve at 10⁶ cycles: σ_max = 0.45·σ_UTS), bearing fretting corrosion (ΔK_th = 2.5 MPa·√m)**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Potentiometer wiper contact contamination (particle diameter &gt; 50 μm) | 8 | Erratic position signal output (signal noise &gt; 200 mV p-p) | Hermetic sealing with IP67 rating, gold-plated contacts (contact resistance &lt; 100 mΩ) |
| Return spring stress relaxation (creep strain &gt; 0.5% at 70°C) | 8 | Non-centering behavior (neutral position offset &gt; 2% of full scale) | Spring steel AISI 302 with stress-relief annealing at 400°C for 1 hour |
