LIMIT SWITCH

Limit switch is an electrical switch used to limit the motion limit position of mechanical equipment. Limit switch is a commonly used small current master electrical appliance, limit switch (stroke switch) is used to control the stroke and limit of mechanical equipment to protect a mechanical switch, mechanical trigger parts and limit switch executive parts will produce mechanical contact, the specific is on or off depends on the combination of stroke switch use of other electrical components to decide, not static. In general, it is necessary to design the circuit according to the electrical components used to achieve A on B off, B on A off.

1. The limit switch refers to the switch assembled in the housing in order to protect the built-in micro-switch from external force, water, oil, gas and dust damage, especially suitable for places with special requirements for mechanical strength and environmental adaptability. The shape can be roughly divided into horizontal type, vertical type and composite type.

2, The limit switch is divided into working limit switch and limit switch, the working limit switch is used to give the mechanism action in place signal. Limit switch is to prevent the mechanism action beyond the design range and accidents. The working limit switch is installed in the position where the mechanism needs to change the working condition. After the switch action, the signal is given to carry out other relevant actions. The limit switch is installed at the farthest end of the mechanism to protect the mechanism from excessive damage.

3, limit switch can be widely used in construction, port, mining and other industries of lifting, transmission machinery space coordinate control and limit, limit switch by high-precision large transmission ratio reducer and its output shaft synchronous mechanical memory control mechanism, sensor composition. 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 use adjustment.
