Key features of our LS2 Double Side Break Switch
Made with a hot‑dip galvanized steel base featuring field‑adjustable mounting provisions, ensuring strong structural support and installation flexibility.
Equipped with maintenance‑free dry‑lubricant bearings and non‑magnetic hardware in all live parts, supporting smooth and dependable operation over time.
High-conductivity copper blades and terminal pads with silver-plated hard drawn copper contacts. Contact pressure is maintained by a stainless-steel coil spring.
The LD2 is available in W Configuration. 2 types are available: Substation switch with individual base frame; Transmission switch on unitized base frame.

Main contacts are silver plated copper to silver plated copper. The copper parts are tin plated when in contact with an aluminum surface. All tinned copper-to-aluminum interfaces are cleaned of oxidation and permanently sealed with an oxydation inhibitor. Self lubricating AgC contacts are available as an option. Contact fingers are self-resilient and do not require any additional springs to provide contact pressure. During a short- circuit, the electrodynamic forces increase contact pressure.
