• Specifiion

• Functions

1.Safety Interlock Control
A primary role is to enforce safety protocols: for example, it may act as an operator presence switch (requiring the operator to be seated and engage the switch before the engine starts or hydraulics activate) or a emergency stop interlock (cutting power to non-essential systems if triggered). This prevents accidental machine activation and reduces injury risks.

2.System Power Regulation
It controls power flow to specific subsystems, such as:
Enabling/disabling auxiliary hydraulic attachments (e.g., breakers, grapplers).
Activating/deactivating comfort features (e.g., cab lights, climate control) without disrupting critical operations.

3.Rugged Environmental Resistance
The IP65 rating and oil-resistant housing protect internal components from dust, mud, water, and hydraulic fluid—common in construction sites. The flame-retardant material also meets safety standards for cab environments.

4.Reliable Electrical Performance
Silver-plated contacts minimize voltage drop and prevent arcing (a common cause of switch failure), ensuring consistent signal transmission even in high-vibration conditions (e.g., during excavator digging or loader bucket operation).

5.Ergonomic Design
The compact size and panel-mount layout fit seamlessly into Komatsu’s operator cab control panels. Push-button or toggle actuation provides clear tactile feedback, so operators can confirm switch activation without visual checks.
