1HE19-12 snap action limits switches are contactors that act as a control switch for contact in valves, pumps, and other devices for controlling the flow of fluids. These types of switches are designed to provide an easy and quick way to start and stop the flow of fluids in an automated system. The construction of this type of switch is also very durable and will provide reliable performance over a long period of time.

The 1HE19-12 snap action switch has two main components - a contactor and a switch movement mechanism. The contactor is made of a metal material that is typically stainless steel or brass. The contactor is connected to a solenoid, which is a device that is used to generate an electric current when a button or switch is pressed. The switch movement mechanism is then used to open and close the contactor. This is done by the actuator, which can be either an electromechanical or an electronic actuator.

The working principle of a 1HE19-12 snap action switch is relatively simple. When an electrical current is applied to the contactor, the solenoid is activated and the contactor will open and close. This is then used to control the flow of fluid in the system. The amount of current needed to activate the solenoid will vary depending on the pressure of the fluid and the flow rate of the fluid.

The 1HE19-12 switch is most commonly used in the industrial applications such as valve and pump control systems, cooling and heating systems, and in other systems that require switching of fluids. It can also be used in residential and commercial applications, but these types of switches are not as robust and durable as the industrial versions. The 1HE19-12 is also used to control flow and pressure in oil and gas pipelines and for remote monitoring applications in the oil and gas industry.

The 1HE19-12 switch is designed to offer high reliability and safety and has been tested to achieve the required standards. The switch is also designed with a built-in safety cut-off device, which helps to protect the system from excess pressure or from being activated inadvertently. The 1HE19-12 switch is normally rated for use in temperatures ranging from -20 deg C to +60 deg C, although some variants may be designed for operation in higher temperatures.

As with any other device, the 1HE19-12 switch should be installed following the manufacturer’s instructions. It is important to ensure that the switch is connected in accordance with the wiring diagrams and that the switch is adequately secured to ensure that it will not move when in use. It is also important to check that the environment in which the switch is being used is suitable for its use.

The 1HE19-12 snap-action switch is a reliable and robust switch that is widely used in a variety of applications where accurate control of fluid flow is required. Its ability to provide an easy and quick way to start and stop the flow of fluids and its durability make it an invaluable part of modern automation systems.
