Working principle of limit switch
working principle: limit switch is an electrical switch used to limit the movement limit position of mechanical equipment. limit switch is a commonly used low-current master electrical appliance.
1. the limit switch (travel switch) is a mechanical switch used to control the stroke and limit protection of mechanical equipment. the mechanical trigger part and the limit switch execution part will have mechanical contact.
2. whether it is on or off depends on other electrical components used in combination with the travel switch, and it is not static. generally speaking, when designing the circuit, according to the electrical components used, it must be a-on and b-off, and b-on and a-off are enough.
3. limit switch refers to the switch assembled in the shell to protect the built-in micro switch from external force, water, oil, gas, dust, etc., especially suitable for those with special requirements for mechanical strength and environmental adaptability local. the shape is roughly divided into horizontal type, vertical type and composite type.
4. the limit switches are divided into working limit switches and limit limit switches. the working limit switches are used to signal that the mechanism is in place. the limit switch is to prevent accidents caused by mechanism actions beyond the design range. the work limit switch is installed in the position where the mechanism needs to change the working condition. after the switch is activated, a signal is given to perform other related actions. the limit switch is installed at the farthest end of the mechanism to protect the mechanism from damage due to excessive movement.
5. the limit switch can be widely used in the control and limit of the three-dimensional coordinate of the lifting and transmission machinery in the construction, port, mining and other industries. the limit switch is composed of a high-precision large transmission ratio reducer and a synchronous output shaft. composed of mechanical memory control mechanism and sensors, wtau series limit switches are widely used in construction machinery because of their small size, multiple functions, high precision, adjustable limit, strong versatility, and easy maintenance, installation, and adjustment.
