SwitchyJr
Power Control Module
SwitchyJr was the competition mount's power-control enclosure. It sat at the back-left of the plate, slightly overhanging and directly above the car's connection point. A 3D-printed, screwed-in clamp underneath secured the overhang.
The connector side faced the outside edge. This kept the connection accessible in an already crowded corner, while the clamp gave the enclosure support beyond the edge of the plate. The box, clamp and cable route need to be considered together; simply copying the box shape misses part of the mounting arrangement.
Files
The competition parts are in CAD/Mount/Switchy Jr/:
SwitchyJr_CompleteAssembly.SLDASMSwitchyJr.SLDPRTClampy.SLDPRTFoot.SLDPRTSwitch_RS2066972.SLDPRTPrintParts/for the exported print files and older tests.
SwitchySr is different. It belongs with Rigby's Platey assembly, under CAD/Rigby/Platey - Electronic Mounting/Switchy Sr/.
Fit and Service Access
The important checks were support beneath the overhang, tool access to the clamp, clearance around the DDT mounting knobs, and space to connect and disconnect the car without pulling on the enclosure. Wiring needed strain relief rather than being held in place by the connector alone.
Electrical switching and wiring are covered by the archived power-system notes. This page records the packaging, not a wiring or pinout specification.
