The D40ML-M1-U-M12 is a type of snap action, limit switch. Snap action limit switches are switches that use a small induced force, such as a spring or a magnet, to create a momentary contact or open circuit between two electrical contacts. Once the force is removed, the contacts will snap back to their original positions. These switches are commonly used in a variety of automated control systems to detect a specified physical event and to provide a signal to activate or deactivate a circuit. It is a low-cost and effective way of sensing an object’s presence or absence.

The D40ML-M1-U-M12 is a single-throw, single pole microswitch with an adjustable lever arm. The switch has both normally open and normally closed contacts. It features a mechanical life of 5 million cycles and an electrical life of 200,000 cycles. The operating force required is low, around 7.5 ounces (212 grams). The contact rating is 20W at 250VAC. It has a maximum contact gap of 0.3mm/0.012 inch and a minimum contact gap of 0.3mm/0.012 inch.

This switch is most often used in the automotive, industrial and electronic industries. Applications for the D40ML-M1-U-M12 include general purpose load control, motor control, instrumentation, traffic and safety controls and audio/video control. In a motor control application, the switch can be used to turn a motor on and off or to reverse the direction of the motor. In a general load control application, the switch can be used to control an appliance by turning it on and off. It can also be used to monitor temperature and switch circuits accordingly.

The working principle of a snap action limit switch is relatively simple. It consists of two pieces, a movable (or movable contact) and a fixed contact. When the switching force is applied, the movable contact is pushed up against the fixed contact. When the force is released, a spring or a magnet will pull the movable contact back towards its original position, allowing the circuit to break or create a connection.

The D40ML-M1-U-M12 snap action limit switch is an ideal choice for controlling general-purpose loads and motors. Its low operating force and long life make it suitable for a variety of applications. Its ability to create a gap between the two contacts while detecting an object’s presence or absence make it a reliable and cost-effective solution for many different industries.
