Steel A/C disconnects
This company's line of standard fusible and non-fused steel A/C disconnects has expanded to include GFCI receptacles, non-automatic switches, and plastic enclosures. Designed to ensure continuous power to A/C units while they are being repaired, the devices are 10,000A IC rated and have pad-lockable doors. The A/C disconnect with an integrated GFCI receptacle is housed in one box instead of two.

Ergonomic switches
This line of single-pole and 3-way commercial and industrial pilot light and lighted handle switches now features an ergonomic external back wire clamp design. With this switch design, there is no need for internal back wiring holes. Instead, the installer inserts the wire under the external clamp, which is serrated for better gripping retention, and tightens the terminal screws to the proper torque value.

Toggle switches
These heavy-duty specification-grade toggle switches feature a high-impact/chemical-resistant rocker and coil compression spring for smoother action. The toggle switches are designed for controlling resistive, inductive, tungsten-filament, fluorescent, and motor loads for AC branch lighting and appliance circuits as permitted by the NEC. The switches also feature a nylon toggle, silver cadmium oxide contacts, a one-piece copper-alloy contact arm, and Brass Phillips/slotted/Robertson combination binding head terminal screws, which accept up to 10 AWG wire.
