Abstract
The utility model relates to a travel switch and specifically to a travel switch having a state indicating function. The travel switch having the state indicating function includes a pedestal and a cover. A contact unit is disposed in the pedestal. The contact unit includes a group of normally open contacts and a group of normally closed contacts. A state indicating device is arranged above the contact unit. The state indicating device connects and cooperates with contact points of the normally open contacts or the normally closes contacts of the contact unit through a spring. In the utility model, the current motion state of the travel switch is showed in a method of signal indication timely, thereby providing references for equipment maintenance personnel. A socket method (such as adopted in connecting an air socket and an air plug) is adopted in installation connection of the travel switch having the state indicating function in the utility model. A user only needs to connect a lead with a plug. When the switch needs to be installed, the user only needs to insert the plug into a socket directly. Therefore, the installation efficiency of the travel switch having the state indicating function is improved substantially.
Description
Technical field
The utility model relates to a kind of travel switch, is specially a kind of travel switch of carrier state deixis.
Background technology
Travel switch, position switch (claiming limit switch again) a kind of is a kind of little electric current master control electrical apparatus commonly used.Utilize the collision of manufacturing machine moving component that its contact is moved and realize connecting or the disjunction control circuit, reach certain control purpose.Usually, this type switch is used to the position or the stroke of limit mechanical motion, make movable machinery by certain position or stroke stop automatically, counter motion, variable motion or back and forth movement etc. automatically.
The action of existing machinery contact travel switch does not have the signal indication, can not effectively monitor the current running status of switch, can not change the switch that damages in time, thereby the normal operation of equipment is brought potential safety hazard.The existing travel switch in current market adopts lead directly to be connected with the switch mode of connection without exception, when changing, needs the process of Repeated Clear Signal-wiring, has seriously restricted the efficient of changing.
The utility model content
To the problem that exists in the prior art, the purpose of the utility model is to provide a kind of technical scheme of travel switch of carrier state deixis.
The travel switch of described carrier state deixis; Comprise a pedestal and a lid; Be provided with a contact module in the pedestal; Said contact module comprises one group of normally open contact and one group of normally closed interlock, it is characterized in that described contact module top is equipped with a state indicating device, and this state indicating device is connected through the normally open contact of spring and contact module or the contact of normally closed interlock.
The travel switch of described carrier state deixis is characterized in that said state indicating device is provided with control circuit, and control circuit can directly connect AC power or DC power supply.
The travel switch of described carrier state deixis is characterized in that the state indicator elment on the said state indicating device adopts light-emitting diode or buzzer, and light-emitting diode or buzzer link to each other with the normally open contact or the normally closed interlock of contact module.
The travel switch of described carrier state deixis is characterized in that said state indicating device is provided with draw-in groove, and lid is provided with projection, described draw-in groove and described projection snap fit.
The travel switch of described carrier state deixis is characterized in that said lid one side is provided with aviation plug, is connected with external cable through aviation plug.
The mode that the utility model makes the current motion state of travel switch indicate through signal reflects in time, and personnel provide foundation for plant maintenance; Aspect the installation connection, adopt inserting mode (like aviation socket and aviation plug), the client only needs lead is connected with plug, can directly plug insertion socket be got final product when changing switch later on, has improved the switch installation effectiveness greatly.
