1DM1

Snap Action

1DM1 is a type of snap-action limit switches that can be used in a variety of applications. A snap-action switch, also known as a micro-switch, is a type of switch that uses concentric springs to move the internal contacts from an open position to a closed position. When the force on the switch exceeds the internal spring tension, the contacts will move from the open position to the closed position. Once that closed position is reached, the contacts will not move until the force is removed.

Snap-action switches are ideal for applications where a reliable threshold must be detected quickly, such as door interlocks, safety sensors, and machine control. 1DM1 snap-action limit switches come with a variety of options, including different contact ratings and mounting styles. These switches are available in both normally open (NO) and normally closed (NC) configurations, which provides flexibility for different types of applications. The 1DM1 also has several mounting configurations, including side, top, and bottom orientations.

Working Principle

The working principle of the 1DM1 snap-action limit switches can be explained as follows:When an external force is applied to the switch, the internal resistive force of the springs is exceeded and the contacts move from the open position to the closed position. When the force is removed, the contacts will return to the open position. This process is what is known as a "snap-action" because the contacts move quickly between the open and closed positions.

The 1DM1 is available in two versions. The first version is a single-pole, double-throw (SPDT) switch. This type of switch has two sets of contacts. When the switch is in the open position, the contacts of the first set are connected while the contacts of the second set are disconnected. When the switch is in the closed position, the contacts of the first set are disconnected while the contacts of the second set are connected.

The second version of the 1DM1 is a single-pole, single-throw (SPST) switch. This type of switch has only one set of contacts. When the switch is in the open position, the contacts are disconnected. When the switch is in the closed position, the contacts are connected. The SPST switch is typically used in applications where a simple on/off function is required.

Applications

1DM1 snap-action limit switches can be used in a variety of applications, including automotive, consumer electronics, industrial equipment, and safety switches. In the automotive industry, snap-action limit switches are used in door locks, transmission shifting, and brake pedals. In consumer electronics, snap-action switches are commonly used in video game controllers and switch products. In industrial equipment, they are often used as machine control switches, such as on lathes and drills.

In safety applications, snap-action switches are used in emergency stop button systems to prevent the machine from operating if a safety hazard is detected. They are also used in fire alarms and automated sensors, where they detect changes in air pressure or temperature and activate the alarms. 1DM1 snap-action limit switches also offer reliable and accurate performance in harsh environments, such as high temperatures, high pressure, or severe vibration.

1DM1 snap-action limit switches are reliable, durable, and easy to install. They provide an economical solution for a variety of applications, including automotive, consumer electronics, industrial equipment, and safety systems.
