Benefits & Common Applications

• High Current Capability
  Able to handle 20 A at 250 VAC, this switch is suitable for powering or switching relatively heavy loads in control panels or machinery.
• Dual Path Switching (DPDT)
  With two independent circuits, you can switch two separate lines simultaneously — useful for reversing polarity, dual circuits, or redundant systems.
• Reliable Snap Action Mechanism
  The internal spring and quick-action design deliver crisp, repeatable switching with minimal bounce — essential for controlling critical loads.
• Robust Construction
  The use of silver alloy contacts, strong mounting, and good thermal tolerance ensures durability in industrial environments.
• Versatile Integration
  The screw-mount form factor and quick-connect terminals make it easy to incorporate into panels, enclosures, or control modules.

Installation & Handling Tips

1. Proper Mounting
   Secure the switch body using the designed screw holes to ensure stability and prevent stress on the actuator.
2. Wire & Terminal Considerations
   Use proper gauge wires matching the 20 A rating and ensure solid connection to the quick-connect terminals.
3. Avoid Overtravel
   While the switch is robust, avoid subjecting the plunger to excessive force or travel beyond its design to preserve its lifespan.
4. Use in Appropriate Environments
   Install in enclosures or with environmental protection in applications where dust, moisture, or debris may be present.
5. Test Before Final Deployment
   Cycle the switch through load transitions to confirm reliable actuation and contact performance.
