Quick Details
Specifications
General Instruction
the switch takes FA series auxiliary switch as its body, which has the advantages of small and delicate with high reliability and high cost performance, the fast on & off device is cleverly designed with mechanical structure, no power supply, flexible and reliable. It is the preferred auxiliary switch for slow-speed mechanisms.
Service Condition
1.Ambient temperature: -50℃~+70℃;
2.Altitude: the installation spot is supposed not to exceed 5000m;
3.Humidity: the average value of relative humidity is max 95%,the
Average value of vapor pressure is max 2.2kPa in condition within 24
Hours; the monthly average value of relative humidity is max
90%,the monthly average value of vapor pressure is max 1.8kPa.
4.Vibration acceleration is max 15m/s2;
5.There should be no evident air pollutions from dust, smoke,
Corrosives and combustible gas, vapor or salty fog
Structure Features
FA series auxiliary switch is made up of multi-units with same structures. the moving contact adopts good phosphor bronze, the stable contact is made of superior brass, and the insulation plate is made of superior inflaming retarding polycarbonate material with high strength, good insulation and heat-resistance. Moreover, the reasonable structure of the switch ensures excellent dust-proof effects. It can realize the functions of on & off instantaneously.
Working Principles
FA series auxiliary switch with fast on & off device is based on FA series auxiliary switch by adding the fast on & off device which drives the switch to realize fast on & off function. When the shaft is rotated 65 ° -75 ° from the off position,the fast on & off device drives the switch body to quick closing to realize NO&NC functions instantaneously, which enhances the breaking
Installation and Operation
1. for the mounting dimensions of auxiliary switches, please refer to the drawing. Customer designs the mounting position of the auxiliary switch on the operating mechanism according to size and position of mounting
Hole.
2. Auxiliary switch has screw hole or screw rod which used for installation and fixation. during the installation and use of the switch, except for the driving force of the rotation of the square shaft, it shall not bear other forces that cause the switch body to bend or impact force.
3.the size of mounting plate and mounting hole can also be customized according to customer requirements.
