Kirby Switch On/Off Press-Lock - D80/1CR Classic 300 Series The bypass layout keeps coolingThis genuine OEM Kirby press lock on off switch restores reliable power control on the Classic and Dual Sanitronic uprights. It latches the motor on or off and holds the setting during use. A failing switch can leave the vacuum dead, shut it off unexpectedly, or lock in the on position. Fitting the correct factory switch brings back safe, predictable starts and stops. A sound switch also holds its setting so the motor stays on until you release it.
