Snap Action, Limit Switches: 11SM401-T Application Field and Working Principle

The 11SM401-T switch is a snap action limit switch, designed for use in a wide range of applications. The switch is designed to be robust, reliable and easy to install, with a variety of mounting and connection options available. Its main purpose is to act as a detection or limit switch, providing feedback to a control system. The switch is normally open and is triggered when the plunger is depressed by an object or force.The 11SM401-T is rated for 250VAC and 4A UL, making it suitable for most industrial applications. It is also rated for an IP65 protection class, allowing it to be used in outdoor applications where the switch may be exposed to wind and rain. The switch is capable of continuous operation at temperatures of -25 to +70 °C.The 11SM401-T has a wide range of applications, and can be used to detect the position of moving parts, such as a door or a hatch. It can also be used to activate a device, such as a machine or a pump, when a limit is reached.The design of the 11SM401-T switch is based on a snap action mechanism, with the actuation button pressed against a coil spring. When the button is pressed, the coil spring opens a set of contacts, closing the circuit. The contacts are made from a silver alloy and are designed to provide a long service life, up to 1010 cycles.The contact may be configured as normally open (NO) or normally closed (NC), depending on the application. If the contact is configured as normally open, when the switch is triggered the contacts will close and the circuit will be activated. If the contact is configured as normally closed, the contacts will open when the switch is triggered and the circuit will be deactivated.The 11SM401-T switch is designed to be operated manually and is suitable for applications where the position of a moving part needs to be monitored or where a device needs to be triggered at a specific point. The switch is ideal for applications such as security systems, access control, machinery control and safety-related systems.The 11SM401-T switch is designed to provide reliable and accurate switch actuations, with a uniform contact resistance that can be relied upon in demanding applications. The switch is designed to be robust and reliable, with a long service life and an IP65 protection class. Its wide range of applications and robust construction make it a popular choice for applications requiring a snap action limit switch.
