4 Pin Momentary Switch

A DIP (dual-inline package) tact switch is a type of switch that is commonly used in electronic devices. These switches are compact and can be mounted on a printed circuit board (PCB) without taking up much space. The 4 pin dip tact switch is a specific size of the DIP switch that measures 4.5mm by 4.5mm. In this article, we will discuss the features and applications of the 4.5x4.5mm DIP tact switch.

Features of the momentary tact switch

The 4.5x4.5mm DIP tact switch is a compact and versatile switch that offers a number of features that make it ideal for use in electronic devices. Some of its main features are:

1. Low-profile design: The 4.5x4.5mm DIP tact switch has a low profile design that makes it ideal for use in compact electronic devices.

2. PCB mounting: The switch is designed to be mounted directly on a PCB, which saves space and makes it easier to integrate it into the device.

3. Momentary action: The switch has a momentary action, which means that it only remains in the on position as long as it is being pressed. This feature is useful for input devices such as keyboards.

4. Long life: The switch is designed to last for a long time, with a lifespan of up to 100,000 cycles.

5. Contact rating: The switch has a contact rating of up to 50mA at 12VDC, making it suitable for use in a wide range of electronic devices.

The 4 pin tact switch is a highly significant and reliable component within the electronics domain. With its distinct 4.5x4.5mm dimension and through - hole design, it offers a unique set of advantages that make it indispensable in numerous applications.

One of the primary merits of the 4.5x4.5mm through hole tact switch lies in its robust mechanical connection. Unlike surface - mount counterparts, the through - hole design involves inserting the switch pins through dedicated holes on the printed circuit board (PCB) and soldering them on the opposite side. This method creates a firm and stable attachment, enabling the switch to endure harsh conditions such as vibrations, shocks, and mechanical stress. In automotive electronics, where components are constantly exposed to engine vibrations and road bumps, or in industrial machinery that experiences significant mechanical movements, the through - hole tact switch maintains its integrity and functionality over extended periods.
