Snap action, limit switches are one of the most versatile and often used sensing devices in control and automation. The 1LS47 is a snap action, limit switch with a wide range of applications and working principles.

The 1LS47 is a type of SPDT (single pole double throw) switch, which can be used to trigger other components when it is actuated. It has two sets of contacts, one normally open contact and one normally closed contact. When the actuator arm is pressed down, the switch will close the normally open contact, and when the actuator arm is released, the switch will open the normally closed contact. In other words, a 1LS47 can be used to control the flow of electricity based on the current state of a circuit.

The 1LS47 is ideal for controlling the opening and closing of doors, windows, and other access points, as well as for monitoring the flow of liquids or gases in pipes or tubing. It can also be used to sense the presence or absence of solid objects in engineering systems, such as automated production lines. The 1LS47 is also commonly used in the control of machines that require precise timing and synchronization, such as motors and engines.

The working principle of the 1LS47 is simple and effective. A mechanical actuator arm is connected to a spring-loaded plunger. When the actuator arm is pressed down, the plunger is forced down, which in turn compresses the contacts. This action creates an electrical connection, redirecting the flow of electricity and triggering other components, such as pressure sensors or electromechanical timers.

The unique design of the 1LS47 makes it ideal for use in harsh and hazardous environments, as it is resistant to shock, vibration, and extreme temperatures. Its small size and low cost also make it a popular choice for applications where space and budget are limited. In addition, the 1LS47 is designed to meet UL, CSA, and other relevant safety standards.

In summary, the 1LS47 is a versatile and reliable snap action, limit switch with a wide range of applications and working principles. Its unique design allows it to be used in a variety of applications and environments, while its compact size and low cost make it an ideal choice for budget-conscious solutions.
