Seat Switches

Request Info

Delta Systems’ seat switches sense operator presence. Used in conjunction with a machine or vehicle’s safety system, operator presence switches provide a fail-safe condition (shutting down the engine, turning off cutting blades, etc.) when an equipment operator is no longer in the seat. Sealed, unsealed and high-cycle-life Hall Effect styles are available. Choose from twist lock or bolt mounting. With decades of proven reliability, our switches are ideal for rugged gas and electric-powered applications.

Typical Applications Include: 

  • Outdoor Power Equipment
  • Utility Vehicles
  • Power Sports
  • Construction
  • Farm & Agricultural
  • Asphalt Pavers/Concrete Mixes
  • Light Industrial
  • Material Handling
  • Off-Highway Vehicles
  • Mining
