Snap Action, Limit Switches - 11SM712-H58 Application Field and Working Principle

Switches are electrical components that are used in a wide variety of applications. The 11SM712-H58 switch from Оmроn is an electromechanical snap-action switch that is designed for use in firm, reliable switching applications. This article covers the 11SM712-H58 switch\'s application field and working principle.

Application Field

The 11SM712-H58 switch is ideal for use in applications where a reliable switch is necessary. The switch is especially well-suited to automotive applications due to its specially designed construction and approval ratings. The 11SM712-H58 is also suitable for many industrial applications. The switch\'s compact design means that it can be easily installed in tight spaces, while still providing accurate and reliable switching functions.

Working Principle

The 11SM712-H58 switch is an electromechanical snap-action type switch. The switch actuator comprises a pair of arms fixed at one end to a central pivot, with the other end connected to the switch contacts. A coil spring is used to maintain the arms at the resting position and supplies the return force for moving the contacts back to the resting position.

When voltage is applied to the coil, it creates an electromagnetic field which attracts the switch arm and overcomes the tension of the coil spring. The arm then moves and closes or opens the contact depending on the type of switch. When the voltage is removed, the switch arm, again under the action of the coil spring, moves back to the resting position and the contacts are in the open state or resting position.

Conclusion

The 11SM712-H58 switch from Omron is a robust and reliable electromechanical snap-action switch, which is ideal for use in automotive and industrial applications. The switch is actuated by a coil spring, which forces the contacts to the resting position when voltage is removed. The 11SM712-H58 is easy to install and provides reliable switching performance in a wide range of conditions.
