Maxiswitch Powerhouse 4-Way Contactor with Heater Socket

Maxiswitch Powerhouse 4-Way Contactor + Heater Socket

The 4-way variant of the Maxiswitch Powerhouse range — UK-assembled grow light contactor built to strict CE standards using high-quality Grasslin timers and GE contactors. Includes an additional always-on heater socket. Safely switches 4 HID lamps from a single timer signal, protecting the timer from direct inductive load.

Why growers choose the Maxiswitch Powerhouse 4-Way:

• 4 controlled mains outlets — right-sized for 4-light setups (e.g., 4 × 600W HPS)
• Heater socket included — always-on socket for heater control alongside lights
• Grasslin timer internals — premium German timer components
• GE contactors — professional-grade contactor internals
• CE-certified UK assembly — built to strict UK electrical standards
• Protects timer from inductive load surges — HID switch-on surges kill cheap timers; contactor absorbs them
• Prevents power overloading — dedicated contactor circuit, not jammed extension leads

Who it's not for:

For single- or two-light setups, a simpler mechanical contactor or plug-in timer is cheaper. For 6+ light commercial setups, step up to the 6-way or 8-way Powerhouse, or MDF 16-way boards. Mains installation must be done by someone competent with electrical work — contactor wiring involves live connections.
