► Warning
1. Use the switch within the specified voltage range. Using the switch outside this range may cause malfunctions and damage, as well as electric shock or fire.
2. Do not exceed the maximum allowable load. Loads exceeding the maximum allowable load may damage the switch.
3. Do not use loads that generate surges. Even if the switch's output circuit has surge protection devices installed, repeated application of surges
may damage it. When directly operating devices that generate surges, such as relays and solenoid valves, use loads with built-in surge
absorbers.
4. Be sure to check the applicable fluid. This switch is not explosion-proof. To prevent fire, do not use it with flammable gases or fluids.
5. Monitor the voltage drop within the switch. If the load operates below the specified voltage, it may fail even if the pressure switch is operating
normally. Therefore, after determining the load voltage, the following formula should be followed.
