This is a replacement switch assembly for the Mastermind GT 10, 16 and 22. Replacing switches requires no soldering - they plug into the circuit board, and replacing switches does not void your warranty.
THIS MODEL IS INTENDED FOR MASTERMIND GTs made in late 2020 or after. These have a connector that plugs vertically into the circuit board (see photos). If you have an older GT where the connector lies flat along the circuit board, we offer a different model of switch for those units. Search for part number MMGT-SA1-OLD.
This switch also can be used for the Mastermind PBC/6X. In PBC/6Xs made in 2021 or later, the switches plug into the circuit board and no soldering is required. In older units, you can still use this switch, but you will need to cut the connector off, strip the ends of the wires and solder them to the pads on the circuit board.
