11. What is NC 30mm push button switch?
Unlike the NO push button, this nc push button switch(normally closed) is closed in a default state, which means it has electrical contact with the circuit.
As the button is pressed, it gets open, and the circuit is open, the switch no longer remains electrically connected.
12. What are the differences between the momentary and latching function of the 30mm push button switch?
A continuous compression is compulsory for the momentary button switch.
As long as the user puts pressure on the switches, they will continue to work.
As the pressure is removed from it immediately, 30mm push button switch will turn off.
Consider an example of an electric drill.
industrial momentary push button switch has broad applications. One of them is in the medical industry. Telephone operators also use them to talk. A momentary switch is actuated only when someone is pressing it – like a doorbell.
On the other hand, latching button switch starts operating as the user switches on and keeps working until the switch is turned off.
This means that it doesn’t require continuous compression from the user.
The application of lockable push button switch is comprehensive, and majorly it is present in home-like central heating switches, light switches, or on stereos.
