Double Throw Fusible Bolted Pressure Contact Switches

Features Geneva dual operator mechanism with mechanical interlocking of two independent switches managed by a single handle. Enables safe source transfer and redundancy in critical circuits.

Geneva Dual Operator Mechanism

The Geneva mechanism is the heart of our double throw switches, providing reliable mechanical interlocking between two independent switch positions controlled by a single operator handle.

This innovative design ensures that only one switch can be closed at a time, preventing dangerous paralleling of sources while enabling safe source transfer operations.

Perfect for applications requiring dual source switching, redundancy, and critical power transfer operations.

Geneva Mechanism Benefits

  • Mechanical interlocking prevents dangerous paralleling
  • Single handle operation for two independent switches
  • Positive positioning with clear indication
  • Fail-safe design for critical applications
  • Robust construction for industrial environments
