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.

Description N/A
  • Our standard vacuum switch line with a variety of electrical ratings available. 10A and .1A are the most common versions and will typically have the shortest lead times. 10A is recommended for direct control of most current drawing devices. The .1A switch selection has gold plated contacts and is recommended for low amperage applications such as PLC and micro controlled interface. Other electrical options are available for specific application requirements.
  • 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.
