What SS-1-FT-4 actually does on a panel
The Omron SS-1-FT-4 is a subminiature snap-action limit switch from the SS family, built for position-detect and end-of-travel duty on control panels, conveyor guarding, and small machine tooling where a compact switch body has to fit alongside a solenoid or pilot device on a crowded DIN layout. Snap-action means the contacts change state at a defined trip point regardless of actuator speed — the snap mechanism gives clean make/break even under slow cam approach, which is what the limit switch class is specified for, and the subminiature form factor lets it sit in tight guarding brackets where a standard-size body would not clear the moving part.
