Snap action, limit switches are commonly used in various industrial and commercial applications. A limit switch is a device used to indicate the position of a movable part, or provide a limit or a safety stop for a mechanism. When the part being monitored moves through its range of travel, it actuates the limit switch, indicating end positions or intermediate points. The most common application of limit switches is in HVAC systems to measure and regulate temperatures, air flow, and pressure as well as to monitor the protection elements of motors and other machinery.

The 1SE1-2 limit switch, manufactured by Honeywell, is a simple and reliable device used to detect and measure relative movement of a part or a system. The device features a movable contact plunger which is activated when the part or system reaches a preset point. The contact then opens, allowing for a variety of useful feedback signals.
The 1SE1-2 has a secure spring mechanism and a one-piece contact plunger for excellent performance and reliable operation. The contact plunger can withstand up to 500 million operations and the construction of the device ensures a long life of smooth and reliable operation.

The 1SE1-2 has a simple working principle that is based on an electrical circuit closure or interruption when the plunger moves from one position to another. When actuated, a metal contact or an armature is allowed to move from one position to another, completing the circuit and thus providing a feedback signal to the associated device. This feedback can be used to control and regulate the position, speed, and other parameters of the system.

The 1SE1-2 limit switch is used in a variety of industrial and commercial applications, including controlling and regulating temperature, air flow, and pressure, monitoring protection elements of motors, manipulating machines, hotel and office automation, paint systems, and with industrial robot and automation systems.

In conclusion, the 1SE1-2 limit switch is a simple device which is widely used in a variety of applications to detect and measure relative motion of a part or a system. It has a secure spring mechanism and a one-piece contact plunger for reliable performance. The device works on the principle of electrical circuit closure or interruption when the plunger moves from one position to another and provides feedback signals which can be used to control and regulate the position, speed, and other parameters of the associated system.
