This momentary switch is a universal push-button control used in vacuum cleaners and power nozzles (Part #622). A momentary switch makes contact only while it is pressed and releases when let go, making it ideal for spring-return power buttons, reset functions, and pedal-style controls.Because it is a universal-type part, it can serve as a replacement across a range of machines that use a standard momentary contact switch. When your button no longer triggers reliably, sticks down, or fails to spring back, swapping in a fresh momentary switch restores crisp, responsive operation. Type: Universal momentary (press-to-make) push-button switch Behavior: Active only while pressed; returns to off on release Use: Power buttons, reset/pedal controls on vacuums and accessories SKU 622 is a versatile repair part. Confirm the terminal layout and mounting dimensions against your original switch before installing.
