What is the difference between normally open temperature switch and normally closed temperature switch?
As can be seen from the name, the difference between them is that when the temperature threshold is not reached, one of their contacts is in a disconnected state, and the other is always in a closed state.
Rice cooker micro switch, what is the function?
1、the key function of the micro switch is to provide precise control effect for home appliances, when the device is switched on and off, we need to achieve it through operational control, and the micro switch is a very good choice in this respect, and other types of switches cannot achieve the precise effect of the micro switch.
2、to ensure the safe and orderly operation, the traditional switch is easy to appear a variety of safety accidents, and the point in the operation, want to meet the needs of consumers from hardware to design, microswitch can be a good balance, and can ensure the safety and stability of appliances in operation.
（一）What is the difference between air switch and circuit breaker?
（二）From the function point of view, what is the difference between air switch and circuit breaker?
What is the core principle of microswitches?
一、It is to complete the disconnection or connection by means of micro-action force.
二、When the force acting on the micro switch continues to become smaller, the corresponding reaction force will also become smaller.
三、The stroke of the micro switch is very short when it is running, so the accuracy of its operation is very high.
What are the parameters of limit switch selection that need attention?
一、Limit switch description
二、switch types, mechanical switches are divided into the following three types:
三、What is SPDT and DPDT?
四、what is dry contact, wet contact?
What is a limit switch?
一、The limit switch is an electrical switch used to limit the motion limit position of the mechanical equipment.
二、 The limit switch is divided into working limit switch and limit switch.
一、Is the daily travel swi
What is the difference between a limit switch and a travel switch?
The limit switch and the travel switch are all position switches, but as an input signal control circuit, the travel switch can also detect the travel within the appropriate distance. Unlike the limit switch, which detects the limit signal, it plays a stopping and protecting role.
The working principle of foot safety switch and its internal structure
The safety foot switch is a switch that controls the circuit by stepping or stepping on the foot, and is used in the control circuit that cannot be touched by the hands to achieve the purpose of operation instead of the hands.
The simple and safe foot switch is actually a built-in travel switch, and when the foot gives a signal, the switch is executed. However, the function of the foot switch in the welding field also plays the role of controlling the output current.
