Description
The Power Switch Board is an essential internal component that houses the physical power toggle and the DC input jack. Unlike simple switches, this board is a dedicated PCB that helps manage the initial current inrush when the printer is powered on, protecting the main motherboard from voltage spikes.
It is specifically designed to fit the rear housing of the Mars 3, Mars 4, and Mars 4 Ultra models. It provides a stable connection point for the 24V power adapter and distributes that power to the motherboard, the cooling fans, and the UV light source array.
Features
Multi-Model Compatibility: A unified replacement part that fits the mounting holes and housing cutouts for Mars 3, Mars 4, and Mars 4 Ultra.
Integrated DC Jack: Features a reinforced barrel jack port designed to withstand frequent plugging and unplugging of the power adapter.
Heavy-Duty Toggle Switch: Equipped with a high-cycle rocker switch for reliable "click" engagement and long-term durability.
Voltage Regulation Support: Includes onboard capacitors to help filter electrical noise and stabilize the 24V input before it reaches the sensitive control board.
Plug-and-Play Installation: Utilizes standardized pin headers for the internal wiring loom, making it easy to swap without soldering.
