Toggle switches are a type of electrical switch which has two terminals (poles) and a lever for an operator to turn the switch on or off by either pressing the lever up or down. The most common type of toggle switch is the SPST (single-pole, single-throw) toggle switch. The 29ET16-3B-K toggle switch is a subminiature momentary action switch featuring both On-Off and Off-On contact configurations. It is a low profile SPST toggle switch with a quick-make and slow-break contact design, allowing the contacts to open or close in an instant while helping to reduce arcing. The 28ET16-3B-K is rated for a maximum voltage of 250V and can handle a current of up to 16A.
The 29ET16-3B-K is ideal for a wide range of applications, including industrial, automotive and consumer electronics. Its small size, mounting holes and snap-in style make it an ideal choice for both professional and hobby-level applications. The switch features a two-piece, non-magnetic plastic case and features a contact-rated temperature of -25°C to 105°C and an insulation resistance of 100MΩ min (at 500V DC).
The working principle of the 29ET16-3B-K toggle switch is based on the electrical contact effect. When the lever is pushed up, the electrical contacts close and the switch is "on". When the lever is pushed down, the contacts open and the switch is "off". In addition, the toggle switch utilizes a contact-rated temperature to ensure reliable operation in applications with varying temperatures.
The toggle switch also features a small amount of contact bounce, which is the bouncing of the contacts when the switch is turned on and off. This helps to reduce arcing between the contacts and helps to ensure reliable switching operation.
The 29ET16-3B-K is a reliable and versatile toggle switch which is ideal for a wide range of applications. Its low profile and quick-make and slow-break contact design make it an ideal choice for both professional and hobby-level applications.
