Snap action, limit switches, like the 1EN42-R7, are designed to perform the same basic function: breaking an electrical circuit at a certain point of operation. They are often used in control and safety circuits, as well as in control systems. Typically, the 1EN42-R7 is a single-pole, double-throw (SPDT) switch. The switch is actuated by a tight tolerance spring, which provides accuracy and repeatability. The current through the switch is determined by the contact material, the force and the coil resistance.

The 1EN42-R7 is primarily used in industrial automation applications, where it allows the user to monitor and control the status of a process. The switches can be used to indicate the open or closed status of a circuit, allowing the automated control system to take appropriate action. For example, the switch could be used to indicate the presence or lack of flow in a pipe or valve, allowing the control system to activate a motor designed to operate the valve or pipe.

The 1EN42-R7 can also be used in home automation, where it is used to switch lights, fans, or other appliances on and off. Home automation systems require precision and reliability, and in this regard the 1EN42-R7 excels. With its tight tolerance spring, the switch is able to provide a consistent level of performance, allowing the user to control the status of their home in a reliable manner.

The working principle of the 1EN42-R7 is fairly simple. When the switch is in the normally open position, the contact at the spring is not engaged. When the force is applied, the contact engages the switch, closing the circuit. As long as the force is maintained, the circuit remains closed. When the force is released, the contact is returned to its normally open position, breaking the circuit.

The 1EN42-R7 is one of the most reliable snap action, limit switches available. Its tight tolerance spring ensures consistent performance, and its ability to switch high currents and voltages make it suitable for a variety of industrial and home automation applications. Its simple operation makes it easy to use, and its low cost makes it a popular choice for many control systems.
