SANY 60309921 D2VW-5L2-1M Excavator Pilot Safety Microswitch
●SANY 60309921 Microswitch Technical Support
●The 60309921 (Model D2VW-5L2-1M) Microswitch (微动开关 / 点动开关 / inching switch / Микропереключатель / Microinterruptor) is a precision waterproof snap-action limit switch engineered for SANY hydraulic excavators.
●Material number 60309921 is mounted inside the operator cabin left or right armrest box console (such as the 60351545 armrest box assembly and 60309922 lower housing). Directly actuated by the pilot safety lockout lever mechanical cam, it opens or closes the electrical circuit supplying the main hydraulic pilot shut-off solenoid valve. When the safety lever is raised, the switch cuts power to the pilot manifold, physically locking all joystick commands and preventing unintended boom, arm, swing, or travel movements while the operator enters or leaves the cab.
●Verify actuator roller lever length, contact configuration (SPDT / 1NO+1NC), lead wire termination / waterproof connector, and IP67 immersion sealing rating prior to order confirmation.
