  • Automotive Controls: Window controls, seat adjustments, mirror positioning
  • Marine Applications: Winch controls, trim tab adjustments, bilge pump controls
  • Electronics Projects: Manual pulse generation, temporary circuit activation
  • Control Panels: Jog controls, manual overrides, test functions
  • Robotics: Manual positioning controls, emergency stops, mode selection
  • Audio Equipment: Momentary mute, channel selection, effect triggers
  • Industrial Controls: Manual valve controls, conveyor jog, equipment testing
  • Model Railways: Turnout controls, signal activation, accessory control
  • Test Equipment: Manual trigger switches, calibration controls
  • Security Systems: Panic buttons, manual alarm triggers

Wiring Configuration

Terminal Identification

  • Terminal 1 (Top): First momentary output
  • Terminal 2 (Center): Common input/output
  • Terminal 3 (Bottom): Second momentary output

Common Wiring Examples

  • Motor Jog Control: Center = motor common, Top/Bottom = forward/reverse momentary
  • Pulse Generation: Center = signal input, Top/Bottom = different pulse outputs
  • Manual Override: Center = control input, Top/Bottom = override functions

Technical Notes

Important technical considerations and usage tips:

  • Momentary operation means switch returns to center OFF position automatically
  • Ideal for applications requiring spring-return operation
  • Waterproof caps provide protection in harsh environments
  • Compact size suitable for space-constrained applications
  • Screw terminals provide secure wire connections
  • Mini form factor perfect for handheld controllers
  • Spring mechanism provides tactile feedback

Installation

  • Drill 6mm (0.23”) hole in panel
  • Insert switch through hole from front
  • Secure with included hex nuts and washers from rear
  • Connect wires to screw terminals as needed
  • Install waterproof cap if environmental protection needed
  • Test momentary operation before final installation

Safety Considerations

  • Voltage Rating: Never exceed 250V AC or equivalent DC
  • Current Rating: Do not exceed 2A at 250V AC or 5A at 125V AC
  • Momentary Operation: Ensure circuit design accounts for spring-return behavior
  • Environmental: Use waterproof caps in wet or dusty conditions
  • Wire Gauge: Use appropriate wire gauge for current load

Included Accessories

Each switch comes with:

  • 2 hex nuts for panel mounting
  • 1 flat washer
  • 1 locking washer
  • 1 waterproof cap for environmental protection
