SEAL - SWITCH (JLG JL8580312)

A worn switch seal can allow moisture or debris to enter the switch housing, leading to intermittent electrical contact or premature switch failure. This aftermarket replacement part references JLG catalog number JL8580312. The seal functions as a barrier that protects internal switch components from environmental contaminants. Its primary mechanical role is to compress against the switch body to form a closed barrier. When the seal degrades, the switch may become unreliable in damp or dusty operating conditions. The item ships at approximately 0.008 pounds. Verify the serial number or application, then call (562) 693-7748.
