Snap action, limit switches are switches that incorporate a mechanical device that supports motion of part of the switch. The device can be either a pin or plunger, or a spring loaded magnet, that is pushed into the body of the switch when it is switched on or off. The switch is already closed or open when the pin is in place and the switch is released. In this way, the actuating shaft of the switch can be stopped in its shortest possible distance, and the switch can be adjusted to fit its particular application.

1LS91 is one of the most popular snap action, limit switches. It is a single-pole double-throw (SPDT) configuration, with two sets of contacts, each operated by a single lever arm on a shaft. Unlike a traditional toggle switch that only controls one circuit, the 1LS91 uses two sets of contacts that can be operated either individually or simultaneously. It is designed with a square base, with two single throw contacts on the opposite side. The contacts can be open or closed depending on the position of the lever arm, which can be moved along the shaft to the desired position. The 1LS91 is capable of switching between different circuits quickly and reliably to meet the requirements of industrial applications.

Working Principle

When the lever arm is moved in one direction, the set of contacts is opened, and when the lever arm is moved opposite, the other set of contacts is closed. The two sets of contacts in the 1LS91 are directly connected to a power source, allowing the switch to be used in applications that need to quickly switch between two different power sources.

The 1LS91 works by pushing the lever arm in one direction when the switch is set to the open position. This raises the lever arm, which in turn activates a plunger that pushes the contacts open. Once the switch is closed, the plunger will be released and the two sets of contacts will be closed. This activation of the 1LS91 allows it to be used in precisely timed applications such as circuit breakers or motor control systems.

The 1LS91 is designed with a temperature range from -55°C to +125°C, which makes it suitable for use in harsh industrial environment. The 1LS91\'s mechanical construction also ensures a long service life and reliable, repeatable operations.

Application Field

The 1LS91 is suitable for a wide range of applications and is commonly used in industrial motor, tray, and battery control systems. Additionally, the 1LS91 is used as a circuit breaker in various types of machinery, as well as in agricultural and military environments. The 1LS91\'s small form factor, robust construction, and accuracy make it suitable for a wide range of applications.

The 1LS91 is also used in medical devices, enabling the switch to provide high switching accuracy and reliable operations when installed in medical grade equipments and systems. Additionally, the 1LS91 is suitable for use in electrical panels, where it can be configured to control multiple circuits simultaneously.

The switch is also commonly used in HVAC, security, and other building control systems, where it can help monitor and control heating and air conditioning systems, as well as help ensure the safety of the occupants. The 1LS91 is designed for reliable operations in harsh and extreme environments, making it an ideal choice for most building control and monitoring applications.

Overall, the 1LS91 is an excellent choice for applications that require reliable, switch operations in harsh environments. Its mechanical construction and design allow it to reliably switch between different circuits quickly and easily, while its small form factor allows it to be used in tight spaces and confined areas. In addition, the 1LS91\'s accuracy and temperature range make it the perfect choice for a wide range of applications. Therefore, the 1LS91 is an excellent choice for a wide range of industrial, military, and commercial applications.
