Snap action switches, which are also known as limit switches, are mechanical devices that are used to control electrical devices or other mechanisms. The 18HM45 is a type of snap action switch. It is designed to respond quickly to electrical changes and provide accurate, lasting, and reliable performance.

Features of 18HM45 Snap Action Switches

The 18HM45 is constructed of durable plastic, with a stainless steel spring that provides resistance to high vibration. It has a contact rating of 12A-125A, which enables it to switch higher currents while maintaining an acceptable level of accuracy. Its maximum operating temperature is 125°C and its temperature range is -40°C to +85°C, making it suitable for operation in all climates.

The 18HM45 also features dust and oil resistance, allowing it to remain operational even in harsh environmental conditions. It is also RoHS compliant, which is a safety standard that ensures that the device does not contain harmful materials. The 18HM45 has a mechanical life of 5 million cycles and an electrical life of 5 million cycles, meaning it is capable of switching on and off up to 5 million times without failing.

Applications of 18HM45 Snap Action Switches

The 18HM45 has a wide variety of potential uses in industrial, medical, and commercial applications. Its compact size allows it to be used in tight spaces or to switch high current capacity while occupying less space than other snap action switches. It is suitable for applications requiring fast switching and reliable electrical connections.

In the automotive industry, the 18HM45 is used to control the opening and closing of fuel injectors, in order to help ensure proper fuel delivery. In the medical field, it can help to monitor and control medical devices such as infusion pumps and respirators. Other applications include controlling door or window locks, controlling the temperature of refrigerators, and operating robots and other automated machines.

Working Principle of 18HM45 Snap Action Switches

The 18HM45 works on the principle of magnetic flux. When the switch is in an open position, it creates an open magnetic circuit, allowing current to flow. When the switch is closed, a magnetic core creates an enclosed magnetic circuit, which disrupts the current. The 18HM45 operates at computer speed, meaning it can switch quickly, responding to changes in just a few hundredths of a second.

The 18HM45 features a trip-free design, meaning that current will continue to flow in both directions even when the switch is in transition from an open to closed or a closed to open position. This makes it an ideal choice for applications that require consistent operation.

The 18HM45 snap action switch is a reliable and versatile device for a variety of commercial, industrial, and medical applications. Its fast switching speed and durable construction make it an ideal choice for both high- and low-load applications. The 18HM45 supports both AC and DC current, making it an ideal choice for a wide variety of purposes.
