# Rotary Switch Module V1

**Type:** Product page · **SKU:** SEN0156 · **Brand:** [DFRobot](https://core-electronics.com.au/brands/dfrobot-australia)
**Page:** https://core-electronics.com.au/rotary-switch-module-v1.html ([markdown](https://core-electronics.com.au/rotary-switch-module-v1.html.md))

A rotary switch is a switch operated by rotation. It is often used when more than 2 positions are needed, such as multi-speed control.

## Pricing

- **Price:** $8.70 (inc GST) — $7.91 AUD, exc GST
- **Quantity discounts:** 6+ $7.51 (exc GST) · 12+ $7.20 (exc GST)

## Availability & dispatch

- In stock, ships same business day if ordered before 2PM (Australia/Sydney).
- We can dispatch 4 today, and up to 200 more in 8–12 days.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN0156:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/SEN0156:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

A rotary switch is a switch operated by rotation. It is often used when more than 2 positions are needed, such as multi-speed control. The Rotary Switch uses an analog input to read the 12 state which saves IO resource for the Arduino. This Rotary Switch Module has 12 positions. Each position has the approprite indicator. You can also adjust metal buckle inside the switch to change the position number. So, it's very flexible to use.

 A rotary switch consists of a spindle or "rotor" that has a contact arm or "spoke" which projects from its surface like a cam. It has an array of terminals, arranged in a circle around the rotor, each of which serves as a contact for the "spoke" through which any one of a number of different electrical circuits can be connected to the rotor. Thus a rotary switch provides greater pole and throw capabilities than simpler switches do. Notice:In order to make it easier for users and more intuitive understanding of our products, we are revising the sensor. A new version of the sensor has the following two features. 1. Unify the digital and analog sensor interface and directly printed A,D on the board to represent analog and digital
2. Each sensor board is printed with an icon to simply illustrate sensor function.
 
 In order to unfity interface, new version analog sensor pin will all be changed(Please see the following comparison chart). So the new version sensor is currently incompatible with I/O expansion boards, but can be compatible with Romeo. We will continue to update. For the inconvenience caused, please understand.
