Snap Action, Limit Switches: I110-SA313 Application Field and Working Principle

Snap action, limit switches (also known as paddle switches) serve a simple yet imporant purpose in a wide range of industries. This particular switch, the I110-SA313, uses a simple mechanism that activates when pushed, closed, or pulled in a specified direction. It can be used as a selector switch, a sensing switch to detect the movement of an object, a signalling device, or as a control switch in industrial devices and machinery.

In terms of physical size and shape, the I110-SA313 is a miniature snap switch with a snap action lever, which is the most common design for this type of switch. It is 22.3 mm long, 17.3 mm wide, and 13.2 mm high, with 2.8mm mounting hole diameter. The contacts are rated to 5A at 125VAC or 2A at 250VAC, with an electrical life of 100,000 operations. Furthermore, it has a maximum contact resistance of 550mΩ, an insulation resistance of 100mΩ, and can operate in temperatures ranging from -25℃~+65℃.

The working principle of the I110-SA313 is the same as that of any other snap action switch. When the actuator is pressed, closed, or pulled in the specified direction, it triggers a set of fixed contacts to move apart or together, with the help of an internal mechanism (spring or lever). This ultimately creates an electrical connection between the two contacts, and the circuit is closed. As the actuator is released, the internal spring-loaded mechanism returns the contacts back to their original position and the circuit is opened.

The I110-SA313 is a reliable, cost-effective switch that is suitable for a wide range of industrial applications. It is commonly used in high-speed machinery, motion and position sensing, lighting control systems, auto doors, power transmissions and other equipment, or any other application where a reliable switching system is needed.

In conclusion, the I110-SA313 is a reliable, cost-effective snap action switch, with a simple working principle based on an internal spring loaded mechanism. It is most suitable for applications in the industry, and can be used as a selector switch, a sensing switch to detect the movement of an object, a signalling device, or as a control switch in various types of equipment.
