Snap Action, Limit Switches

The 91MCE18-S2 snap action, limit switch is a unique combination of a mechanical operator and other electrical components like relay, transistors, and connectors, along with a variety of other components. It is basically a multi-zone switch, which allows for a wide range of user control over the electrical circuit. It is designed to quickly and efficiently switch an electrical circuit in response to a user input.

The 91MCE18-S2 snap action, limit switch is typically used in industrial applications, like the automation of process control systems. The device can be used to detect the movement of mechanical objects such as a conveyor belt, a robotic arm movement, or a position control switch. In addition, it can be used in safety applications such as the shutdown of a machine in the case of emergency. It is also used in consumer and home appliance applications like washing machines and refrigerators. And, it is even used in medical devices such as electrocardiographs and patient monitors.

Working Principle

The 91MCE18-S2 utilizes a trip mechanism based on the principle of progressive contact closure. This mechanism allows for the reliable opening and closing of contacts for a switch with a long service life. The actuator of the switch, commonly referred to as the plunger pick-up, applies pressure to the mechanical operator when it is depressed or activated by a user. This action causes the switch to rapidly open and close, thus turning the electrical circuit on and off.

The 91MCE18-S2 snap action, limit switch also features a self-cleaning, reed switch mechanism. This special feature prevents the switch from becoming blocked or jammed due to dirt or other accidental causes. The reed switch is designed to resist temperature extremes and is extremely reliable, making it well suited for industrial applications.

Aside from the trip mechanism, the 91MCE18-S2 also features an active tension spring. This spring increases the force of the operator, allowing the switch to maintain a tight contact closure even at high speeds. This ensures that the switch can be operated even when the speed of the equipment has increased significantly.

The 91MCE18-S2 snap action, limit switch also includes a number of protective measures. This includes current sensing, which prevents potentially damaging current overloads. It also includes fault monitoring, which can detect any potential problems in the electrical circuit and provide actionable insights to the user. Finally, it includes a backup contact system, which ensures that even in the event of a power failure, the switch will remain in the same position.

Conclusion

In conclusion, the 91MCE18-S2 snap action, limit switch is a versatile device designed for a wide range of applications. It utilizes a trip mechanism based on the principle of progressive contact closure, and a reliable reed switch that prevents the switch from becoming blocked or jammed due to dirt or other accidental causes. It also includes a number of protective measures, such as current sensing and fault monitoring, to ensure that the switch can safely and reliably switch an electrical circuit in response to a user input.
