<strong>Pressure</strong> <strong>Switches</strong><br />

Air Systems - <strong>Pressure</strong> <strong>Switches</strong><br />

• Used for air or water cut-in on rising pressure<br />

• Designed to ground the ignition on gas engine driven pumps and compressors when the maximum pressure has been<br />

reached, or to act as low pressure alarms, or to prevent pump operation at low pressure<br />
