Vacuum Switch

Vacuum Switch

Vacuum Switches are an interface between a vacuum signal and an electrical circuit. The switch is used to monitor the vacuum signal and change the electrical state of the switch at a pressure.

Vacuum Switch Options

  • V5100 Series Subminiature Vacuum Switch

    V5100 Series Subminiature Vacuum Switch

    • Due to recent market challenges, we have made the decision to standardize our microswitch specifications and phase out certain low-volume options. Our commitment is to continue offering high-quality and reliable products, now uniformly featuring a standard 15-amp microswitch rating. As part of these updates, our V5100 series will undergo changes, with select part numbers available for a final purchase opportunity until our existing inventory runs out. We fully recognize the impact of this change on your selections and are prepared to assist you in identifying suitable alternatives within our revised product range. These changes will help us ensure that our pressure switches maintain our standards of efficiency and performance, aligning with your needs and expectations.
    • Factory preset options are available. Please contact us for specifications and a custom part.
    • Adjustments can be made to the switch by turning the flat head screw. Adjusting preset switches is not recommended.
  • V5300 Series Low Differential Vacuum Switch

    V5300 Series Low Differential Vacuum Switch

    Due to recent market challenges, we have made the decision to standardize our microswitch specifications and phase out certain low-volume options. Our commitment is to continue offering high-quality and reliable products, now uniformly featuring a standard 15-amp microswitch rating. This update specifically affects our V5300 series, which will be discontinued entirely. We fully recognize the impact of this change on your selections and are prepared to assist you in identifying suitable alternatives within our revised product range.

    Moving forward, the V5100 series will be our primary focus. The key distinctions between the V5100 and the discontinued V5300 series include changes to the spade terminals in the V5100 series, along with a higher differential. These changes will help us ensure that our Vacuum switches maintain our standards of efficiency and performance, aligning with your needs and expectations.

  • V5500 Series Solid State Vacuum Switch

    V5500 Series Solid State Vacuum Switch

    • This vacuum switch uses a Hall Effect Sensor to determine the mechanical movement of the diaphragm. There are no electrical contacts in the switch to wear or fail. This switch requires an AMP 102241-1 connector and external (not provided) circuitry to function. Please see VX Series installation instructions for more information.
    • Vacuum switches apply signal pressure to a diaphragm that is opposed by a spring force. When then vacuum signal force is greater (deeper vacuum = more force) than the spring force it reaches its set-point (also called “On” pressure), the internal mechanism moves and changes the electrical state.
    • When the switch trips, the normally open circuit closes and the normally closed circuit opens. The switch will remain in this state until the vacuum signal drops below its reset point (also called “Off” pressure).
    • The difference between the “On” pressure and the “Off” pressure is defined as the Differential or Hysteresis of the switch. This is an important characteristic for applications such as vacuum switch-controlled vacuum pump systems. For instance, the consumption and capacity of the system along with the differential of the switch will determine how often the pump runs.
    • Factory preset options are available. Please contact your salesperson or distributor for specifications and a custom part number.
    • Adjustments can be made to the switch by removing the round cover and turning the flat head screw. Clockwise adjustments will lower the Set point (bring the setpoint closer to atmosphere). Counter clockwise adjustments will raise the setpoint (take the setpoint deeper into vacuum). Adjusting preset switches is not recommended. Do not back out the flat head screw above flush with the body.
