Snap Action, Limit Switches are used as component sensors in a variety of automation systems. The 1478618-3 is one such device, and it is a micro switch released in 2008 by Honeywell. The device has a variety of features designed to spark automation of many processes.

The 1478618-3 operates on an SPDT (Single Pole Double Throw) design, with a hermetically-sealed mechanism that is inserted into the body of the housing when the contact is actuated. The device has an actuator that snaps to a predetermined position when a set amount of pressure is applied. This is what makes it a "snap action" switch and why it is used most often for safety switching applications where precise actuation is necessary. It also makes it easy to detect when the contact has been actuated.

The 1478618-3 can be used to detect various types of movement. These include linear movement, rotational movement, surface movement, load detection, and other types of general purpose actuation. The switch is often used to detect whether the door of a machine or system has been opened or closed, or if the surface of a robotic system has been occupied. It can also be used to detect when a fill level is complete, when a button has been pushed, or to detect any other type of motion.

The 1478618-3 comes with a variety of different working principles that provide a range of response characteristics. The device can be made to respond more quickly or slower through its fast-action position or slow-action position. It can also be configured to release in different increments depending on its application needs. Depending on the application, these switches can be configured to release at various pressure points.

The 1478618-3 is RoHS compliant and has a current rating of 5 A and contact rating of 250VDC. It can be kept in a wide temperature range, from -25°C to 78°C, and its force range can go up to 1.5N. In addition, the 1478618-3 features a dielectric strength rating of greater than 1000Vrms and a mechanical lifecycle of over 5 million operations.

The 1478618-3 also features a variety of mounting options, including threaded mounting and standing mounting. The threaded mounting option allows the switch to be screwed into a surface and the standing mounting option allows the switch to be mounted on stems or on machines. Additionally, the device is IP 67-rated, ensuring the highest level of protection from debris, dust and water.

In conclusion, the 1478618-3 is an SPDT micro switch with a hermetically sealed mechanism that is inserted into the body of the housing. It is a snap action switch and is most often used for safety switching applications where precise actuation is necessary. The switch can be configured to respond quickly or slowly and is also RoHS compliant and IP67 rated. It offers a number of mounting options and a wide temperature range with a mechanical lifecycle of over 5 million operations. Its features make it a great choice for a variety of automation processes.
