Winners Elec's core business is the manufacture and sale of wiring devices such as switches and outlets, along with built-in outlets, multi-outlets, and other communication devices, while also supplying smart wiring devices and smart distribution boards designed for smart-home systems in apartments and other residential buildings.
As of 2023, product mix by revenue was wiring devices 38.9%, multi-outlets 43.0%, smart wiring 7.1%, EV chargers 0.7%, and other products 10.3%, meaning wiring devices and multi-outlets together accounted for more than 80% of sales.
On the distribution side, the company sells through large retail channels including E-Mart, Lotte Mart, Homeplus, and Daiso, plus roughly 360 dealers for its B2C network, and since 2023 it has also entered the B2B market for large construction firms following a supply agreement with Lotte Construction.
Backed by long-accumulated technical expertise and numerous patents, the company is regarded as having top-tier domestic manufacturing capability, pursuing a strategy of premium product lines that emphasize safety and convenience to achieve higher profitability than peers.
Building on its wiring-device technology, the company has recently expanded into EV-charging-related products such as charging outlets, slow and fast chargers, and charger power-distribution systems, seeking new growth drivers.
In April 2025, it signed an online supply contract with Coupang to expand its e-commerce channel, and in September of the same year it signed a supply contract for automatic water-meter components, extending beyond traditional wiring devices.
Amid this diversification, on March 31, 2026, the company changed its name from Winners to Winners Elec.
The controlling shareholder is Winners Holdings LLC (100% stake), of which 70% is held by the IBK-TS Exit Fund No. 2, jointly managed by TS Investment and IBK Bank, while CEO Kim Chang-sung and executive Kim Gun-sung hold 28% and 2% respectively, reflecting a substantial financial-investor presence.
