Seat Switches
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
