These days, many devices turn on automatically - whether you approach, touch, or even just speak to them. But for certain devices, nothing beats the reliability of a good old rocker switch, ensuring safe, manual operation.

Advantages of rocker switches: 

  • They are designed to eliminate accidental activation. 
  • The status of the switches is clearly visible both from the actuator position and the indicator light.
  • The switches consume no power when in the off position.
  • They ensure dependable on/off operation for any device.

Beyond reliability, there are several features that make rocker switches a great fit for a wide range of devices.

Marquardt 1930 series rocker switches: Why they stand out

  • Longevity: With mechanical life of 50,000 cycles, the switches are electrically rated to handle up to 10(8) A at 250 VAC. Even under higher loads of 20(4) A at 250 VAC, they ensure reliable performance for a minimum of 10,000 cycles.
  • Protection Rating: The actuator side is rated IP65, ensuring robust protection against dust and water. The terminal side is rated IP40, suitable for enclosed installations within devices.
  • Operating temperature range: The switch can endure temperatures up to 105°C internally and up to 55°C on the actuator side. Both sides are cold-resistant down to -30°C.
  • Inrush Current Handling: Capable of managing up to 120 A when switching capacitive loads.
