Snap Action, Limit Switches

A snap action, limit switch is a form of mechanical switch used to regulate and control numerous applications. It’s characterized by quick and efficient response when triggered by a moving component, such as a lever or pin, making them ideal for use in controlling start/stop operations or adjusting speed and direction. Here, we’ll discuss the various applications and working principles of a 1EN1-8 snap action, limit switch.

Applications

A typical application of 1EN1-8 snap action switch is in motor control circuits, where the switch’s quick response and adjustable setting can help to regulate motor speed and direction accurately. This type of switch is also well-suited to limit control systems, to halt the motion of certain process elements at preprogrammed upper and lower limits. This can be especially useful in operation with cranes, lifts, hoists and other such machinery, for accurately controlling the operating range of the component.

In addition, 1EN1-8 snap action limit switches offer a useful combination of speed and accuracy for use in robotics and automation. Preprogrammed positions along the device’s adjustable range can facilitate fast and efficient adjustment for components in automated devices, ensuring part or product uniformity over multiple cycles.

Working Principle

The 1EN1-8 snap action switch works by responding to the presence of an actuating element, such as a lever or pin, when the switch is operated. As the actuating element approaches the switch, the switch’s internal components react and force the contacts to either open or close. Releasing the actuating element reverses this process and causes the contacts to open or close again depending on the direction of the actuating element\'s approach. This allows the switch to perform a series of operations, opening and closing its contacts to control and regulate power through a circuit.

The 1EN1-8 snap action, limit switch is capable of providing up to 10mA at 24V DC and is built to UL, CSA and TUV standards for safety. The switch chassis is made from nickel-plated copper, and the contact is made from copper-nickel alloy. This type of switch is available with or without a housing, and features terminals for easy connection to an external circuit.

Conclusion

The 1EN1-8 snap action, limit switch is a highly-versatile mechanical switch which offers quick, efficient and accurate control over a range of equipment and processes. Its ability to open and close contacts rapidly and precisely make it a popular choice for motor control circuits, limit switches, robotics and automation applications.
