311SM704-H2

Snap action, limit switches are a type of switch that houses an internal mechanism that helps the switch to activate or deactivate. The 311SM704-H2 is one of the many sub-types of snap action, limit switches on the market. It is designed to be highly reliable, operate with a low force, and have a long mechanical life. This makes them ideal for industrial applications, particularly those that involve machinery, including factory automation and robotics.

The 311SM704-H2 utilizes a plunger mechanism powered by a spring to cause the switch to activate when a mechanical force is applied to the plunger. The plunger is held in a flush position against the switch body, but when a force is applied, the plunger compresses the spring and snaps into an open position, thus initiating an electrical signal through the switch. This snapping action is how these switches got their name.

The 311SM704-H2 is a single-pole, double-throw (SPDT) switch meaning it features two outputs, one for when the switch is activated, and one for when the switch is deactivated. The contacts on the switch are made of a durable material with a high contact life and are designed to operate with a low initial force in order to prevent malfunctions due to vibration or shock. The switch is also designed to reset itself to its original position after a power cycle.

The 311SM704-H2 is useful in a variety of applications such as machine tool control, industrial robotics, machine monitoring, factory automation, and other industrial uses. Some of these applications require accurate and repeatable operation as well as a long life expectancy and reliability.

The 311SM704-H2 is not suitable for applications in which a low force is not required, such as those applications which require frequent adjustment or require a light touch to activate. It is also unsuitable for harsh environments, such as those containing corrosive gases or liquids, due to its susceptibility to wear.

Overall, the 311SM704-H2 is a reliable and long-lasting limit switch that can be used in a variety of industrial applications. Its plunger mechanism and spring design ensure reliable performance, and its tightly-sealed cover helps to prevent dust and dirt from getting into the switch. Its low force operation and high contact life making it an ideal choice for those seeking a durable and reliable switch.
