Push button switch mainly refers to light touch key switch, also known as light touch switch. The Push button switch is an electronic switch, belonging to the category of electronic components, which first appeared in Japan [called: sensitive switch]. When it is used, it puts pressure on the operation direction of the switch to meet the conditions of operating force. The switch function is closed and connected. When the pressure is cancelled, the switch is disconnected, and its internal structure is realized by the force change of metal shrapnel.
The push button switch is composed of insert, base, shrapnel, button and cover plate. The waterproof touch switch adds a layer of polyimide film on the shrapnel.
The structural characteristics of the button switchThe structure of the button switch: It is composed of a button cap, a return spring, a fixed contact, a movable contact, a shell and a pillar connecting rod.Normally open contact (moving contact): refers to the contact in the original state (the electrical appliance is not subjected to external force […]
The reason why the button switch is not sensitiveThe key switch refers to a switch that uses a button to push the transmission mechanism to make the moving contact and the static contact press or disconnect and realize the circuit changeover. In electrical automatic control circuits, it is used to manually send control signals to control contactors, […]
Working principle of the push button switchThe operating force of the key switch is related to the state of the reed. The starting force is directly proportional to the compression distance of the reed. When the reed is compressed to 5% – 70%, the operating force suddenly decreases, accompanied by a “ticking” sound. There are generally […]
