There are many types of structures for light touch switches, which can be divided into ordinary button type, mushroom head type, self-locking type, self-resetting type, rotary handle type, with indicator light type, with light symbol type, and key type. There are single button, double button, three button, and different combination forms, usually using a building block structure, consisting of button cap, reset spring, bridge type contact, and shell, usually made into a composite type, with a pair of normally closed contacts and normally open contacts, Some products can increase the number of contact pairs by connecting multiple components in series.

The structure of a light touch switch can be mainly divided into five parts: a cover plate, a button, a spring, a base, and a pin. Among them, the button refers to the place where external force is applied; The shrapnel is a key component of a light touch switch, and the on-off of the switch is caused by changes in the force acting on the shrapnel; Pins refer to the connection between a light touch switch and a circuit, usually consisting of five pins, paired in pairs, and one pin used for grounding. When the switch is correctly applied force, the four pins are connected to make the circuit conductive. However, when the switch is not properly pressed by external force, the four pins are not connected in pairs, causing the circuit to be disconnected.
