This is a TE Connectivity standard industrial toggle switch from their general-purpose panel mount series. It's a DPDT (double-pole, double-throw) on-on switch with solder terminals designed for 120V AC panel installations in control cabinets and equipment enclosures. Critical verification: confirm the 5A @ 28V dc rating is adequate for your actual load current, as 120V rating indicates voltage withstand capability, not current capacity at that voltage.
