A touch switch is a special type of switch that, as the name suggests, operates via touch. In other words, you don’t have to necessarily press enough a touch switch. Just touching it should trigger the circuit to open or close.

Touch switches are frequently used in lamps and wall-mounted light switches. They offer a clean, low-profile design that many consumers and business owners prefer over traditional mechanical switches.

How Touch Switches Differ From Mechanical Switches

Mechanical switches, on the other hand, require greater physical force to open and close the respective electrical circuit. There are typically two layers of conductive traces within a mechanical switch. To close the electrical circuit, you must press the mechanical switch hard enough so that these layers meet.
