Snap action, limit switches, commonly referred to as snap switches, are electromechanical switches used to control circuit operations in applications where a momentary switch is needed. It is designed for applications such as sensing the presence of objects, detecting the opening and closing of doors and windows, and limit switch applications. The D2MQ-4L-105-1 is one such type of snap action, limit switch.

The D2MQ-4L-105-1 utilizes a roller-plunger contact mechanism. This means that when an object passes through the field of the switch it triggers the contact of a plunger. The plunger rests on a cylindrical roller that remains at rest until the object passes by it. The plunger then moves against the action of an internal spring and makes contact with the cylinder, thus completing the circuit.

The plunger can be wired for snap action. This simply means that the plunger will remain in contact until the switch is activated. When the switch is activated, the contact pulls away from the cylinder and the circuit is broken. This is useful for applications such as sensing when a door is opened and then detecting when it is closed. If the switch is wired for limit application, the plunger will remain in contact until the switch is activated, but will not re-establish contact until the switch is reset.

In regard to application fields, the D2MQ-4L-105-1 can be used in industrial processes such as factories, automotive, mining and other operating businesses. The most common similar switch applications involve limiting the motion of doors, windows, and other operable partitions. The switch can also be used to sense heat, measure electric current, and regulate electric motors. The level of current that the switch can support depends on its power rating.

The D2MQ-4L-105-1 is a reliable switch since it\'s rated at a minimum of one million operations, making it suitable for extended or continual use in machine control. The switch also has a rated current of 4 amps @ 125/250 volts, allowing for a wide range of use possibilities. This can also provide both a normally closed and normally open contact, allowing for versatile application.

The D2MQ-4L-105-1 switch is well suited for switch applications utilizing high current in an extremely small package. The switch has a compact design with a roller-plunger contact that expands its applications both in industrial and commercial settings. Furthermore, it is extremely reliable, with a rating of one million operations, making it suitable for use in a number of circumstances.
