Volteck Rotary On/Off Dimmer Switch
Rotary dimmer switch from Volteck’s Italian line, letting you turn a light on or off and adjust its brightness with a single twist knob — built in polycarbonate and polypropylene for dimmable incandescent and halogen lighting.
Features
- Rotary Dial Control — A single twist knob combines on/off switching with smooth brightness adjustment, rather than requiring separate controls.
- Polycarbonate and Polypropylene Construction — Durable plastic housing holds up to repeated adjustment and everyday wall contact.
- Flame-Retardant Material — Formulated to resist ignition, adding a margin of safety at a point in the circuit where heat can build up.
- 150 Watt Capacity — Sized for standard incandescent and halogen fixtures in residential lighting circuits.
- Italian Line Design — Compact modular styling matching Volteck’s Italian-pattern switch and outlet series for a coordinated look with matching plates and accessories.

Application Instructions
- Switch off the circuit breaker feeding this line before starting — never wire a dimmer with the circuit live.
- Confirm the wires are dead with a voltage tester before making any connections.
- Confirm the fixture uses dimmable incandescent or halogen bulbs — this dimmer is not rated for all lamp types, and LED or CFL bulbs need dimmer-compatible versions to work correctly.
- Connect the wiring to the switch terminals, then mount the switch into its box or modular plate.
- Restore power at the breaker and test the rotary control through its full on/off and brightness range.
