A tactile switch allows electricity to flow in an electrical circuit by manually pressing the operating section. The switch is used to supply input signal to actuate a device or equipment. It is designed with a small footprint suited for mounting onto the surface of printed circuit

boards (PCBs) made to connect electronic components to form electronic circuits (Figure 1). The switch activates when pressed and then turns off when released. This action is called ‘momentary action’ and can only be performed at low voltage and low current.

There are many different types of tactile switches, also known as tactile push switches or tact switches, used in a variety of applications including household appliances, office equipment, commercial equipment, and industrial machinery.

There are optional features such as size (external dimension), board mounting, and sealing structure for users to select for their applications. A tactile switch is literally a switch that users can “feel a click sense of touch”.

<Click response>

A click response of a button is the most characteristic feature of a tactile switch that lets users

feel the response of the operation from a switch. A clicking feel is generated from the contact

dome embedded in the switch. How large an operation stroke and how sharp a click sense of

touch depends on the materials and shapes of the contact dome.

<High Durability>

The contact dome also acts as a movable contact in a tactile switch. The resistance value

(contact resistance) which is generated between a movable contact and a fixed contact when a

switch is turned on can be stabilized by using specific materials, surface processing, and shape

enabling high durability capable of withstanding 100 thousand to 10 million times of use.

Models

There are two types of tactile switches: Standard tactile switches and sealed tactile switches. The
sealed tactile switches are dust-protected and water-resistant to withstand harsh environmental
conditions. They are further sub-categorized into two types: PCB insert hole terminals type
and PCB surface mounted terminals type. For PCB insert hole terminals type, terminals are
inserted into holes on the PCB and are fixed by soldering. For PCB surface-mounted terminals
type, terminals are surface-mounted and soldered on the PCB. These switches can be
transported in a standalone package, or using a taping packaging method where a carrier tape
holds the switches in place with clearance between them.
Other variations include horizontal push button type, long-stroke type, and ultra subminiature
type switches and many more, ranging from different shapes and specifications that cater to
various applications
