Abstract
Within a welding helmet, an easily removable electronic quick change ('EQC') cartridge is retained into an integral cartridge housing. The EQC cartridge has slots on its top which can accommodate flanges from the housing, and tabs on its sides for insertion into slots of the housing. The tabs are located on the ends of an elastic spring bar which is inside the EQC cartridge. Switches connected to the spring bar by an elevated support lie above the EQC cartridge, which when compressed internalize the tabs inside the cartridge. When the EQC cartridge is positioned within the housing, the switches are released and the tabs extend through the slots of the housing.
