CONTACT (Yale YT220000778)

YT220000778: A worn electrical contact can interrupt current flow in a switch or relay, leading to intermittent operation or total circuit failure. The aftermarket replacement part cross-references Yale part number YT220000778. This contact serves as the conductive interface that completes or breaks an electrical path when actuated. Over time, pitting or oxidation on the contact surface increases resistance, which may cause overheating or arcing. In a typical usage context, repeated switching cycles gradually erode the contact material until the connection becomes unreliable. Verify the serial number or application, then call (562) 693-7748. The part is listed under the Yale catalog reference for electrical contact applications.
