Membrane Touch Switches: What are They and What do They do?

Definition of Membrane Touch Switches Membrane touch switches are sometimes referred to as membrane switches or touch switches. Generally, a membrane touch switch is a momentary electrical on/off switch for activating and de-activating a circuit. Membrane touch switches are thought to have momentary action because they operate under conditions of normally open, push to close, …

Embedded LED PCBs: What are They and What do They do?

A Definition of Embedded LED PCB’s Light emitting diodes (LEDs) are semiconductor diodes. LEDs belong to the group of electroluminescent luminaries, and they generate light by recombining charge-carrier pairs in a semiconductor with an appropriate energy band gap. LEDs are utilized in both industrial and consumer markets because of their low operating voltage and power, …
