momentary illuminated tact button switch classifications
Mar 03, 2023
Momentary illuminated tact button switches are a type of pushbutton switches that incorporate an illuminated feature. They are commonly found on consumer electronics, such as on calculators, and serve as user control feedback for a device's operation.
Momentary illuminated tact button switches are typically constructed of polyamide and/or polyester materials. The material chosen is largely determined by the application, as polyamide switches are more common in industrial applications, while polyester switches are more commonly found in consumer electronics.
Illuminated momentary tact switches are typically rated for anywhere from 5 mm to 12 mm of travel. This is an important factor to consider when selecting a switch for the desired application, as the amount of travel will affect how easily the switch can be triggered by the user.
Illuminated momentary tact button switches are available in a wide range of colours, such as red, green, and yellow, as well as in single and dual polarity versions. The dual polarity versions feature an illuminated component that switches direction when the switch is activated.
The switch’s operation is triggered by its applied force, which can range from approximately 300 gF to 1,200 gF depending on the model. Momentary illuminated tact switches are also available in momentary or latch versions, with latch versions being those that are held in the activated position until it is released or the power supply is disconnected.
In terms of ip ratings, momentary illuminated tact switches can come in a variety of levels of protection from dust, water and weathering. Most are rated from IP40 to IP67, though higher ip ratings may be available for certain applications.
Lastly, most illuminated momentary tact switches are either surface mount or through-hole versions, depending on the application. Surface mount versions are typically faster and simpler to install, while through-hole versions offer a greater level of electrical insulation and are usually preferred in high-voltage applications.
