Where this switch actually sits on the machine
The Omron SS-01GL1375-FD is a subminiature snap-action limit switch from the SS series, used as a position-confirm or end-of-travel detector on small automated fixtures, door interlocks, and consumer-appliance or light-industrial moving subassemblies where the panel footprint is tight and the actuator has to read a cam or ramp. On the order code, the SS-01 prefix marks the SPDT (single-pole double-throw) contact form, so the same switch services either a NO or NC logic path off the common terminal — one body covers two wiring choices on the panel.
What the ordering-code tail tells the cabinet builder
The trailing FD suffix on SS-01GL1375-FD differentiates the actuator style and terminal orientation from other SS-01GL13 family members — matching the suffix is the only way to keep the actuator geometry and the solder/PCB footprint the panel was drilled for, so the cross-reference is code-specific, not family-level. Because the body is subminiature, the rated electrical endurance is the figure that drives the spare-parts decision rather than the headline mechanical travel — this class of snap switch is rated for a defined electrical ops count under load, so any high-cycle application (door interlock on a packaging line, for example) needs that number on the datasheet before the BOM is frozen.
