Antunes Controls' Gas Pressure switches monitor gas pressure. The models are available in high pressure and low pressure single gas switches. Pressure range varies from 1 psi to 15 psi. Each switch is adjustable within its range, as shown on the range scale on the front. The latch position in the reset type models, and level indicator position in the recycle type models show whether the switch is on or off. High gas pressure switches break the electrical circuit when pressure rises above the indicated preset pressure. The reset latch should be latched in the ''on'' position if the gas pressure in the switch chamber is below the indicated high setting.Features:Mount Horizontally - Does Not Require Accurate LevelingAvailable in Automatic Recycle or Manual Reset Easily visible On-Off Indicator1-15 psi Adjustable Range35 psi Maximum Surge Pressure Rugged Die Cast Aluminum Construction CAPACITY TABLE ModelsRangesNatural or LP.
