DIP Switches

Definition

DIP Switches are miniature switches that are mounted onto PCBs and used to make settings on electronic devices.

Their name comes from having the same shape and array of terminals found in integrated circuits (dual inline package), thus abbreviated to DIP.

Features

Small Size Low Profile The standard size is 2.54 mm for the distance between neighboring terminals (pitch), and 3.5 mm for the height. We have also been able to miniaturize this down to a pitch of 1.25 mm.
High Contact Reliability DIP Switches are only used to change settings and therefore are not manipulated often. We have designed our DIP Switches with the optimal materials and mechanisms to maintain high contact reliability.
Automatic Mounting We utilize the same packaging as other components (stick, taping, etc.) so that the same mounting equipment can be used for automatic mounting.

DIP Switches are categorized as setting switches, and the setting conditions are output as ON/OFF signals.

Models

There are three operation methods for DIP Switches: Sliding Types, Piano Types and Rotary Types.
Each of these categories then has two terminal types depending on the method used to mount the switch to a PCB: PCB Insert Hole Terminals and PCB Surface Mounted Terminals.
The shape of the operating part is either Flat or Convex for Sliding Types, Short Lever or Long Lever for Piano Types and Flat or Shaft for Rotary Types.

1. Operating Part

There are three different types of switching methods based on the operating part: Sliding Types, in which the operating part is slid, Piano Types, in which the operating part is pushed down and Rotary Types, in which the operating part is rotated. There are also variations in the shape of each operating part within these three categories.

Convex Types Flat Types Flat Types with Seal Tape
Piano Types
Short-lever Types Long-lever Types
Rotary Types
Flat Types Shaft Types Cone Types Wheel Types

2. Terminals

Terminals vary based on the number of contacts, whether PCB Insert Hole Terminals or PCB Surface Mounted Terminals are used, and whether the Standard Pich (2.54 mm) or a Half Pich (1.27 mm) is used.

Mounting Methods
PCB Insert Hole Terminals PCB Surface Mounted Terminals
Pitches
Standard Pich (2.54 mm) Half Pich (1.27 mm)

Select the terminals, pitch and height based on the components that will be on the PCB along with the switch.

Structures

1
Cover
The cover is connected to the base to protect the internal mechanisms of the switch.
2
Strikers
Use an implement with a fine tip to set the strikers to the ON or OFF positions.
A contact force is applied to the wiper to maintain stable contact between the wiper and the contact.
3
Wiper
The wiper is a V-shaped moving contact.
The wiper moves along with the striker to either open or close the connection between the two contacts and turn the switch ON and OFF.

4
Contact Terminal
The contact terminal is built into the base.
There are two types of terminals: ones that are inserted into insert holes on a PCB and ones that are mounted on the surface of a PCB.
5
Base
The base is molded with contact terminal into a single unit. It protects the inside of the switch along with the cover.
