Rotary Wafer Switch

NSF Controls is a leading UK manufacturer and supplier of switches and solenoids.

What is a Rotary Switch?

Our rotary switches are highly versatile, featuring multi-pole, multi-position, and multi-functional capabilities. Standard rotary wafer switches are suitable for use in applications up to 300 Volts.

NSF offer a variety of rotary switch configurations with different index mechanisms and wafers, depending on the current and positions required. Customisation includes terminations- solder lug, vertical or right angled P.C. tags, shaft configurations and contact material.

Rotary Wafer Switch Design Considerations

  • Provided the switch is used within it’s electrical ratings the electrical life expectancy for our standard product range is 10,000 cycles, 1 cycle is 0-360-0 degrees.
  • Silver alloy contacts will increase this to 20,000 cycles.
  • Mechanical life expectancy is 20,000 cycles.
