Kill Switch Assembly

Subteam: ElectricalSubsystem: Custom ElectronicsAssembly: Kill Switch AssemblyCars: CR21, CR22, CR25, CR26I, CR26E

Purpose

Assembly line covering the master switches and their mounting.

Function

Groups the cockpit-mounted and external master switches required by the rules, with their case and wiring.

Design Process

No part-specific design process is documented. The Custom Electronics subsystem design process applies: 1. Collect the sensor list from every subteam, agree location and type with the designer who needs the data. 2. Split sensors between ECU and dash based on which parameters are engine-critical. 3. Size the charging system and validate it. A custom current measurement board (50 A bidirectional sensing chip, inline on the rectifier-to-PDM wire) measured what the rectifier actually puts back. 4. Build the datalogging parameter list with rates, then check CAN bus load. 5. Validate on a mock endurance: average battery voltage 13.4 V, minimum 12.1 V excluding cranking on CR26I.
