Vacuum switches apply the vacuum signal to a diaphragm that is opposed by a combination of spring forces. When the signal force is greater than the spring force it reaches its set-point (also called “On” pressure), and 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 moves back to its reset point (also called “Off” pressure). The difference between the “On” and “Off” pressure is defined as the Differential or Hysteresis of the switch.

• This vacuum switch uses a smaller micro switch that has small terminals coming out the top. The Differential is lower and electrical cycle life is longer than the standard F5100 switches, however the overall amperage rating is lower.
• 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.

• 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.
