The Advantage Of SMD LED Tact Switch
Jun 27, 2022
As we all know the SMD type illuminated tact switch has compact size, it has the more advantage to packing and storage, it is usually used the taping packing for the machine bulk assemble.
The SMT illuminated tactile button has mini size and light weight, it is convenient for soldering compare to the through hole type led tact button, because of the SMD illuminated switch is press close to the PCB board, so it is not easy to waggle.
The SMD led illuminated button switch is fit for mass soldering operation, it has sable reliability, the low failure rate;of course ,some of engineer will choose the through hole as for the soldering and cost consideration.
The SMD momentary LED tact switch has four lead terminal, it is a normally open circuit, when you press down the PCB mount illuminated tact switch, the led tact switch will be closed, it is close and open the circuit via the inside metal dome to protect the load carry capability.when you withdraw the force, it back to the closing state.
