Snap Action, Limit Switches are used in a variety of applications. The 1SM23 is one such type of switch, designed mainly for use as a limit control switch in gearbox enclosures, hoists and cranes. The 1SM23 switch is able to react to very small movements, making it ideal for monitoring the position of a gear in an enclosed gearbox.

The switch works by activating a small, metal actuator that snaps open and closed when it comes into contact with the moving gear. The actuator contains two springs that act like leaf blades. As the gear turns, the actuator moves with it, compressing and releasing the spring as it does. When the gear reaches its limit of travel, the actuator snaps into place, activating the switch.

The 1SM23 switch can also be used as an overload safety device, which will immediately shut off power to a machine if it becomes overloaded. This helps to protect both the gearbox and the machine itself from damage. It is also commonly used as a temperature limit switch, which will shut off power to a machine if it reaches a certain temperature.

The switch is designed to be highly reliable and durable, with a current rating of 10A AC at 250V and up to 50 million operations. It is also resistant to dust, moisture, vibration and shock. The switch is UL listed and RoHS compliant, making it a safe and reliable choice for many industrial applications.

The 1SM23 switch is a versatile and reliable option for a variety of applications. It is robust, easy to install and can provide reliable protection for both the machine and the gearbox. With its wide range of applications, it is easy to see why the 1SM23 is such a popular choice for industrial and commercial applications.
