• Latching power relay with DPDT double-pole, double-throw contacts, plus
  • quick-connect or screw terminals
  • flyback voltage protection, and
  • printed circuit board for convenient mounting.
• May be used with model railroad 'snap' switches for position feedback, signal lights or routing frog power.
• Latching feature ensures that this relay will maintain its same position when system power is turned off.
