Product details
This genuine VacuMaid SR40 Control Board (Part #PC120STSW) is the replacement low-voltage control board for the VacuMaid SR40 central vacuum power unit. Its standout feature is the integrated on/off switch built directly into the board, giving you manual control of the unit right at the power head in addition to the standard inlet and hose-handle switching.
The board manages the low-voltage signaling that starts and stops the motor, responding to your wall inlets and handle. When an SR40 unit fails to power on, runs continuously, or no longer responds to the inlet contacts, a worn control board is a frequent culprit.
