Item Details

  • The HYPERTHERM INC 128642 is a manufacturer-certified Start Switch Replacement Kit designed for the internal electrical pilot arc trigger switch assembly within industrial handheld plasma cutting torches. This component functions as a momentary contact electrical micro-switch that restores mechanical responsiveness and safe contact closing within the torch body to prevent intermittent firing failures or pilot arc termination.

Features

  • Momentary contact electrical micro-switch closure mechanism
  • High-dielectric housing resists thermal cycling, ozone, and chemical solvents
  • Silver-alloy contacts prevent pitting or micro-welding during rapid-arc cycles
  • Integrated pre-terminated lead wires eliminate the need for field soldering
  • Direct synchronization with Hypertherm 002244 Mechanical Safety Trigger Assembly
  • Low-voltage control pilot loop operation
  • Internal plunger-driven actuation responsive to external safety trigger compression
