The Classic Army Electronic Trigger Switch (ECS) is a direct replacement or upgrade trigger control unit designed for Classic Army Nemesis series AEGs and compatible models fitted with electronic trigger systems. This essential electronic component replaces the traditional mechanical trigger contact assembly, enabling smoother trigger response and advanced firing mode control. 
 
Product Overview
The Electronic Trigger Switch is a small, PCB‑based unit that interfaces between the trigger and the gearbox motor in Classic Army airsoft rifles with electronic fire control systems (commonly referred to as ECS or MOSFET systems). It replaces the stock trigger contact assembly and restores or improves electrical performance in Nemesis AEGs, helping ensure reliable firing and mode switching.
 
Key Features
Direct Replacement for Classic Army Nemesis ECS: Designed to fit models from the Nemesis range that use an electronic trigger system, this switch restores or replaces a worn or faulty trigger control board. 
Electronic Fire Control: Replaces mechanical trigger contacts with an electronic system for more consistent trigger response and durability over time.
Supports Programmable Modes (Where Applicable): Works with Classic Army’s ECS/MOSFET circuits that offer semi‑auto, full‑auto, and burst fire programming (mode selection via trigger programming on supported Nemesis models).
Improved Reliability: Reduces arcing and wear associated with traditional metal contact triggers, contributing to longer service life and cleaner electrical switching.
Plug‑and‑Play Replacement: Designed to mount into the original trigger position and connects to existing wiring in compatible Classic Army Nemesis guns (refer to your model’s schematic for correct wiring).
