Snap Action, Limit Switches:

A Snap Action, Limit Switch is a type of switch which is used to actuate mechanical parts of a machine. It is typically used for controlling a circuit when a certain position has been reached, or for controlling a mechanical device when a certain action has occurred. It is able to turn a circuit either off or on when a certain limit or contact substrate has been reached.

The TL8012-S1220SKM is a popular snap action limit switch. This snap action switch has been designed to provide reliable operation and long-term performance in various applications, such as: Circuit interruption, Feeder control, Emergency stop, and tank level protection. It features a pressure type actuator, provides an extended life expectancy, and an adjustable release angle.

When used in an electrical circuit, the TL8012-S1220SKM allows electrical current to flow when an actuator (or plunger) has been moved to the closed position. An internal terminal block provides easy electrical connector access, whereas a lever arm allows for adjustment to the desired switch actuation position. The limit switch is designed for positioning installation and works with both AC and DC currents.

In terms of mechanism, the TL8012-S1220SKM is typically spring loaded and uses a small change in position in order to actuate the mechanical function. When the plunger is pressed and the limit switch is actuated, the switch will open or close according to the wiring of the circuit. The mechanical movement of the plunger is activated by either a lever or roller actuator.

The TL8012-S1220SKM limit switch is typically used in automation, safety, and control applications such as AC motors, pumps and compressors, and OEM machinery, among others. Its small design and long operating life make it an ideal choice in a range of applications. This type of switch is suitable for a wide range of temperatures, from -5°C to +55°C.

In terms of working principle, the TL8012-S1220SKM operates on the basic principle of a Closing-action switch. It opens and closes a switch when its plunger has been moved to a certain position. Most typically an angular contact is made when it is closed, and if the plunger is actuated then the switch will open or close depending on the wiring of the circuit.

Therefore, the TL8012-S1220SKM snap action limit switch is the ideal choice for a range of applications, including AC motor, pumps and compressors, and OEM machinery. It is small in size, has a long operating life, and is suitable for a wide temperature range. It operates on the premiss of a closing-action switch, using a plunger to turn the electrical circuit either on or off when a certain limit or contact substrate has been reached.
