The 8804K13 is a commercial designation for the MS35058-26 aircraft toggle switch, commonly supplied under Safran/Eaton aerospace hardware channels. It is a MIL-SPEC, heavy-duty, sealed toggle switch used in aircraft electrical control panels and avionics systems.

It is an SPDT (single pole, double throw) switch with a momentary function, typically configured as ON–NONE–(ON). The MS35058 series is widely used across business jets, turboprops, and military aircraft systems where reliable switching under vibration, temperature variation, and repeated cycling is required.

The AN30 reference indicates an alternate aviation designation (legacy AN/MS standard cross-reference) used in older aircraft parts catalogs and interchange listings.
