Snap action, limit switches, such as the 7SE1-T, are essential components for an array of systems and machines. The 7SE1-T is a single-pole, double-throw (SPDT) switch with a filter magnet and a filter capacitor. It is used to provide an airgap between two electrical signals that need to be isolated. The 7SE1-T is a reliable and durable switch, making it suitable for a wide range of applications.

Applications

The 7SE1-T is most commonly used for applications that need precise control and reliable operation. This switch is used in railroad crossings, electronic door locks and openers, home and office automation systems, industrial instrumentation, and many other applications. The switch can also be used to operate air conditioning systems, positioning systems, and safety interlocks. In addition, the switch is widely used in medical and military equipment.

Working Principle

The 7SE1-T switch is a non-latching, single-pole double-throw (SPDT) switch. It is designed to provide a switch for the purpose of signal separation and isolation. The switch is designed to actuate when the armature is displaced from its neutral or off position by the force of a magnet or a capacitive sensor. When the outside voltage is applied to the armature, a controlled current flows through the switch, allowing the switch to be triggered.

When the armature is pulled towards the magnet, a filter capacitor is inserted between the two poles of the switch in order to reduce contact resistance. This reduces the current flowing through the switch, allowing it to be triggered. When the capacitor is inserted, the external voltage is dropped and the switch is closed, which initiates the switch action.

The switch contacts of the 7SE1-T switch consist of silver alloys, ensuring a low contact resistance and a long life. The switch also features a lever arm, which is used to protect the contacts from wear and tear. The lever arm also allows for easy and precise operation.

Conclusion

The 7SE1-T switch is a reliable and dependable switch, suitable for a wide range of applications. It is a non-latching SPDT switch that requires no external voltage to operate and provides precise control. The silver alloy contacts provide low resistance and a long life, while the lever arm ensures easy and precise operation. The switch is ideal for a variety of applications, including railroad crossings, electronic door locks and openers, home and office automation systems, industrial instrumentation, and many others.
