I recently acquired several Taiwan Alpha DPDT foot switches from Rapid (UK). Due to their unresponsiveness on eBay regarding the same switches, I ended up purchasing a larger quantity than planned.
These switches are similar in function to those found in most contemporary pedals. They effectively manage 'soft' latching states. Being double throw, these switches allow for a toggle setup, enabling the option to be normally closed (the Boss standard) or normally open, providing full operational flexibility.
Upon arrival, I found the switches aesthetically pleasing. However, I felt a bit disheartened when I realized they clicked rather positively, leading me to initially believe they were latching switches. However, they are indeed marked as momentary switches.
The core of the inquiry revolves around their design as low-force variants intended specifically for guitar pedals.
The product description states:
This robust momentary foot switch offers a soft touch action and operates electrically silently, making it ideal for scenarios where switch noise would disrupt, such as guitar pedal boards, PA systems, and keyboard foot switches.
- Low actuating force
- No 'clunk' sound during actuation in amplified setups
- Perfect for foot pedals used in music applications
- Allows equipment control while keeping hands free
- DPDT contacts
- Momentary action
Despite this, I found the positive click to be louder than I expected, possibly louder than most other switches I've used. I wonder if I received a different variant as there isn't a clear identifier distinguishing the genuine switch; it merely has a hand-stamped 'AJ2'.
I might need to wait until Tuesday to test these, considering the logistical disruptions in the UK this weekend.
A search for 'AJ2' yields no information online regarding the seller or manufacturer. The differentiator between the two options seems to be a 027 suffix for these and an 011 for the standard switches.
I'm curious if anyone else has experience with either type of switch or any relevant insights.
While these switches don't feel overly stiff, they do require a click-through action, which was unexpected. The manufacturer emphasizes their silent operation, but they might be misrepresenting the mechanical feedback; they don't compare in quietness to the relatively silent switches used in devices like the Zoia or Analog Drive, which would likely produce a mechanical click during ambient performances.
Regardless, I might end up using them, so I'd appreciate any recommendations for quieter alternatives if I decide to change. Before evaluating their in-situ performance, I need to ascertain whether the stamped 'AJ2' identifies them as the model I ordered or the noisier version.
I have slim hopes, but it doesn't hurt to ask; my searches on modwiggler have yielded no results.
Manufacturer Part Number: SFF--20R-M-027.
I plan to connect several of these dual switches or possibly incorporate them in a microcontroller-based MIDI project, aiming to enhance functionality for effects pedals while maintaining a compact footprint.
If you're unable to answer the specific inquiry, please feel free to share any DIY footswitch pictures, information, or tips regarding switches with a pleasant feel (should be 10mm radius for the tops).
Footswitches, suggested by their name, are controlled using the user's foot. Other terms like foot pedals or pedal switches are also used. These switches come in various types and serve multiple functions.
Footswitches are usually preferred over regular switches because they offer better convenience, especially when both hands are occupied. A prime example is a car's gas pedal; while driving, hands are required for steering, thus making the foot pedal valuable for accelerating or decelerating without hindering hand operations. Beyond automotive applications, various cutting and shaping tools in industrial settings also utilize footswitches to enhance user safety and ease-of-use.
This article provides insights into various types of footswitches, their applications, as well as the pros and cons of using them, in addition to guidance on where to find the best footswitches in India.
A variety of footswitches can be found in the market, and selecting the right one that suits your specific requirements is crucial. Not all footswitches are suitable for every task. Here’s a look at the different footswitch types and their typical applications.
Commonly called variable speed footswitches, foot pedal potentiometers share similarities with regular foot pedals but primarily control the speed of connected devices. They are generally used alongside variable-speed motors.
Pressure on the foot pedal potentiometer determines the electric motor's speed, adjusting it accordingly. These are typically employed in cutting machines, shearing machines, and sewing machines.

Also recognized as air actuators, foot switch bellows serve in potentially hazardous environments. They enable safe control of electrical circuits from a distance, ensuring user safety. When the foot switch bellow is pressed, air moves through the tube to the switch element, facilitating electrical connections.
Typically constructed from durable PVC, foot switch bellows are strong enough to be utilized in moist or unsafe conditions where traditional electrical switching poses challenges or safety risks, making them suitable for settings like battery charging areas, garages, and laboratories.

USB foot pedals function through a USB connection with computers or laptops, acting like an input device. They come in various configurations such as single, double, and even triple switches, ensuring user comfort and convenience.
Programming these foot switches is user-friendly, allowing consumers to set individual switches. They are compatible with operating systems like Linux, Windows, and Mac OS (a proper PC emulator is needed for initial configuration on Mac). USB foot switches are widely utilized for image capture and are prominent in call centers and police control rooms.
As implied by their name, these footswitches endure significant pressure and cater to heavy-duty industrial environments. Their design focuses on providing users with optimal performance while minimizing production downtime. Engineered to be oil-tight and dust-proof, these switches can open and close circuits safely, even in the absence of guards or while using front treadles.
Applications for heavy-duty footswitches span across heavy machinery operations, industrial settings, medical devices, and production lines.
A multi-pedal footswitch features two, three, or even up to four pedals, typically constructed from cast aluminum. Its design aims to protect the device it connects to while providing a precise operational point for machinery. Depending on whether they have a plastic or metal base, multi-pedal footswitches can feature different contact configurations.

Footswitches come with distinct advantages and disadvantages. Let’s explore some of them.
Footswitches are utilized for various reasons, including:
They facilitate multitasking by keeping both hands free, simplifying operations.
They save space as they are positioned near the feet during use.
Constructed from PVC, footswitches are sturdy, durable, and reliable.
Being foot-operated reduces the chances of cross-contamination compared to hand switches, making them a more hygienic option.
Operating the switches is straightforward; a simple foot press is enough to turn them on or off.
These switches can function efficiently in various environments without compromising safety.
They provide high stability, aided by their low-profile design.
Despite their advantages, footswitches also carry certain drawbacks, including:
Some individuals find hand-operated switches more convenient and may view footswitches as uncomfortable.
They tend to be bulkier compared to other types of switches.
Using a foot to operate a switch may lead to slipping issues.
Footswitches generally cost more than standard switches.
Unintended triggering can occur, so caution is needed since they are foot-operated.
Although they function well in various climates, direct water exposure should be avoided.
When connecting multiple footswitches, consider using a stabilizing plate.
