Push button switch refers to a switch that uses a button to push the transmission mechanism to make the moving contact and the static contact press on or off and realize circuit switching. The push button switch is a kind of electrical appliance with simple structure and wide application. In electrical automatic control circuits, it is used to manually issue control signals to control contactors, relays, electromagnetic starters, etc.
How push button switch work?
The working principle of the push button switch is that the external force transmitted by the button forms a force for manufacturing transmission inside the switch. The moving contact and the static contact can be connected or disconnected by pressing the button. And his specific use is to better control the switching of the circuit, so as to ensure the safety of the user’s electricity consumption. The push button switch can be used as a switch to start the device or as a power switch.
Push button switches have a wide range of applications and a variety of uses. But they operate similarly. When we apply pressure to the button actuator, the inner spring is depressed. Contacts connected to the springs connect to electrical contacts on the lower end of the switch to open or close the circuit. Depending on the switch, releasing the button or pressing it again will retract the spring and return the circuit to its original state.
The initial state of the button circuit can be turned on or off, depending on the application. The type of switch also depends on the application.
The type of push button switch
Self-return:In a simple way to understand, a self-return switch is a switch that can be reset automatically. After the switch is pressed, it will return to the original state when the hand is released. Similar to a computer power button.
Self-locking:Self-locking switch means that the switch has its own machine locking function. Press it down, and the button will not spring back to the initial state after you release it. It is locked at this time. You need to press the button again to unlock and restore the original state.
Where to use the button?
Button switches can be used in automation equipment, robots, rail transit, logistics, elevators, electronic semiconductors, new energy, construction machinery, electricity, machine tool equipment, etc.
