Dual-in-line package switches, also known as DIP switches are electronic packages that consist of a series of tiny switches. DIP switches come in three types: normally open, normally closed or three stages. They can have different pole and throw configurations such as single pole single throw (SPST), single pole double throw (SPDT), double pole single throw (DPST), or double pole double throw (DPDT).

Various types of DIP switches available in the market are standard DIP, piano DIP, right angle DIP and surface mount DIP, rotary-coded DIP switch and sealed DIP. DIP switches are an alternative to jumper blocks and their main advantage is that they are quicker to change without any loss of parts.

Some important parameters you must consider before you buy a DIP switch are:

1. Electrical switch specifications: maximum current rating, maximum AC voltage rating, maximum DC voltage rating, and maximum power rating
2. Terminal types available such as quick connect or blade, surface mount technology, straight PC pins, right angle PC pins and side PC pins
3. Features of a DIP switch: imprinted markings, tape and reel packaging, CE certification, CSA certification, UL listed, dustproof, weather resistant or waterproof
4. Operating temperature of DIP switches

Buy customized DIP switches to meet your requirements

You can also buy DIP switches customized to your needs, if standard DIP switches available in the market do not meet your requirements.

I recommend: Grayhill is a leading customized DIP switch manufacturer that produces surface mount DIP, rotary DIP, standard and half pitch DIP. U.S. Electronics is another leading manufacturer that offers customized DIP switches.

Tips & Tactics

Helpful advice for making the most of this Guide

• •  Check for the number of on-off positions you want in a DIP switch because the number of positions available is equivalent to the number of actuators available on the DIP switch.
• •  Check for the installation instruction available for DIP switches.
