Abstract
In accordance with the present invention, the ignition cutoff assembly includes fork switch 48, ignition coil kill circuit 50, upper bracket support clamps 55, switch activation collar 58, rod 67, upper bracket 73, and lower bracket 76. Fork switch 48 is a commercially available lever-actuated microswitch capable of signaling ignition coil kill circuit 50 upon actuation by switch activation collar 58. Ignition coil kill circuit 50 comprises commercially available electronic circuitry including at least one high voltage transistor 40a and/or 40b or 41a and/or 41b and/or 41c and/or 41d. Upper bracket support clamps 55 are commercially available clamps made of metal, plastic, or other suitable material capable of retaining upper bracket 73. Upper bracket 73 is custom made of metal, plastic, or other suitable material capable of providing a mounting location for fork switch 48. Lower bracket 76 is made of metal, plastic, or other suitable material capable of providing a mounting location for rod 67. Rod 67 is made of metal, plastic, or other suitable material capable of actuating fork switch 48 upon predetermined travel of fork upper section 61 and fork lower section 64. Switch activation collar 58 is made of metal, plastic, or other suitable material capable of adjustment on rod 67 to actuate fork switch 48 upon motion of rod 67.
