Issue Summary

Item 9, an ON-(ON) toggle e-switch, has a listed part number of 100SP2T8B13M1QEH but is not in manufacture or available for purchase from any retailer. 100SP2T1B1M1QEH looks to be a valid alternative switch, but has a smaller diameter housing - 1/4-40 0.112in (2.845mm) opposed to 15/32-32 0.469in (11.9mm). This switch is exclusively used in the hydraulic isolation panel and nowhere else in the build.

Confirmed using https://www.e-switch.com/product/100-series-miniature-toggle-switch/ Screenshot attached.

Contributor guide

Research direction
Verify the specifications of the original switch (100SP2T8B13M1QEH) and the proposed alternative (100SP2T1B1M1QEH) to ensure they are compatible with the hydraulic isolation panel design. Check dimensions, electrical ratings, and mounting requirements.
