INTOCK SWITCH ASSY

HP RM1-8499-000CN cartridge door switch is the replacement switch identified for the cartridge door in HP’s M525 printer service documentation. It is listed as switch SW501 and described as an interlock switch.

Opening the cartridge door activates the switch. During a service check, the printer’s control-panel display can be observed for a response, helping identify whether the door-switch circuit is registering the door’s position. This part is intended for service replacement of the specified switch in the M525 family described in the manual.
