7SE1

7SE1 is a type of electromechanical switch commonly used to detect the presence of an object or position of a mechanism. The switch consists of two parts: a movable contact lever and a stationary contact. When the switch is in the home position, it maintains a connection between the contacts. When a force is applied to the movable lever, the two contacts separate creating an open circuit.

These switches are mainly used as limit switches in applications where a precise position of a moving object needs to be monitored. For example, they may be used to detect the position of a handle in a machine or to determine the closed position of a valve. The 7SE1 switch’s snap-action design enables the contacts to snap open or closed when the lever force is applied. This design feature makes the 7SE1 switch well-suited for use as limit switches in industrial control applications.

The 7SE1 switch is classified as a snap action switch because it is designed to have a relatively short duration between the time the switch is operated and the point when the contact open or closes. This type of switch is useful for applications that require a quick response to changes in the environment.

The working principle of the 7SE1 switch is based on the magnetic force produced by a coil. When the coil is energized, a magnetic force is applied to the movable contact lever. This force causes the lever to move from its home position and separate the two contacts. When the force is removed and the movable lever returns to its home position, the contacts close again completing the circuit.

The 7SE1 switch is a reliable and cost-effective limit switch option for many applications due to its snap-action design, sturdy construction and simple principle of operation. It is also easily customized with a variety of contact materials, configurations and housing options making it suitable for use in a wide range of applications.
