Snap action limit switches are incredibly widely used. They are one of the most reliable and cost effective switches available, and they are typically found in industrial process control and automation systems, among other applications. Snap action limit switches consist of two metal contact strips (or electrodes) which move together along a rail and are tapped by an armature which is actuated by a plunger when a predetermined limit is reached. When the limit is exceeded, the snap action switch is triggered and the contacts of the switch are switched off, meaning that the power supply is either cut off or that the power flow is reversed.

The snap action limit switches typically have one to three sets of contacts, meaning that the power flow can be either limited or reversed. These switches can be used to control any type of machinery, from HVAC systems to industrial manufacturing, and they come in a range of sizes and configurations, meaning that they can be used for virtually any application.

The 1LS19 series of snap action limit switches are designed for use in industrial processes, and they feature robust, corrosion-resistant housings and gold-plated contacts for reliable performance. The 1LS19 series has a microswitch body which can be operated with an external actuator, and the microswitch is triggered when an armature (controlled by the actuator) moves past the contact points. The 1LS19 series is suitable for a wide range of applications, including motor/valve/motor control, temperature control and motor protection.

The working principle of a 1LS19 snap action limit switch is relatively simple. When a mechanism requiring protection reaches a predetermined limit, or when a predetermined limit passes, an armature connected to the switch trips the switch\'s contacts. This triggers an electro-mechanical response which can be used to start or make another process, or to cut off or reverse a process. Depending on the application, this can be used to activate a motor to start or stop, or to switch off or reverse an electrical field.

The 1LS19 snap action limit switch is a reliable and cost effective switch which is suitable for a wide range of applications. With its robust design and gold-plated contacts, this switch can be used in a wide range of industrial processes, offering a reliable and economical solution to process automation and control.
