LilyPad Slide Switch AYZ0202: Compact Sewable Control for E-Textiles
The LilyPad Slide Switch AYZ0202 is a robust and discreet control component designed specifically for integrating power control into wearable electronics and e-textile projects. As part of the LilyPad ecosystem developed by Leah Buechley and SparkFun, this component allows users to easily turn circuits on and off within fabric-based projects using conductive thread. Its compact size, low profile, and large, conductive sewing pads make it ideal for both hobbyists creating custom garments and businesses developing commercial e-textile products.
Key Features
- E-Textile Compatibility: Designed with large, rounded pads specifically for sewing into fabric using conductive thread, eliminating the need for traditional wiring or soldering.
- Low Profile & Compact Design: The small footprint and slim profile ensure the switch integrates smoothly into clothing or accessories without bulky protrusion.
- Simple On/Off Functionality: Provides straightforward manual control for connecting or breaking a power circuit (SPDT configuration).
- Durable & Washable: The component is designed to withstand normal wear and tear and can be integrated into projects that are carefully hand-washed after the battery is removed.
- Versatile Integration: Compatible with 3V or 5V systems, suitable for standard lithium-ion polymer (LiPo) batteries commonly used in wearable tech.

Usage Instructions
The LilyPad Slide Switch AYZ0202 functions as a simple interrupt in your power line.
Step-by-Step Integration:
- Plan Your Circuit: Identify where you need to manually control power flow (e.g., between a battery holder and a set of LEDs).
- Connect Power Source: Using conductive thread, sew from the positive (+) terminal of your battery pack to one of the outer pads of the slide switch. Ensure secure stitching.
- Connect Load: Sew from the middle pad of the slide switch to the positive (+) input of your component (e.g., the ‘+’ pad on a LilyPad LED board).
- Complete the Ground Loop: Connect the ground (-) sides of all components back to the negative (-) terminal of your battery pack using conductive thread.
- Test: Slide the switch actuator back and forth. In one position, the circuit should close and power your components; in the other position, the circuit should open and turn them off.
Q: Is this switch waterproof?
No, the switch is not waterproof. While e-textile projects can often be hand-washed carefully once the battery is removed, the switch mechanism should ideally be kept dry to prevent corrosion and maintain functionality.
Q: What is the maximum voltage I can run through this switch?
The maximum rated voltage is typically 12V DC, but it is primarily designed and tested for standard e-textile operating voltages of 3V to 5V (e.g., a single LiPo cell).
Q: Can I solder wires to the pads instead of using conductive thread?
Yes, the pads are tinned and can be soldered to for permanent installations using thin, flexible wires if desired, though conductive thread is the intended application method.
Q: I am a business buyer. Do you offer bulk discounts or alternative connectors?
Yes, please contact our sales team for inquiries regarding bulk pricing (MOQ applies). We also offer traditional PCB-mount slide switches for non-textile applications.
Q: How does this differ from the standard push-button component?
A slide switch maintains its state (ON or OFF) until manually changed. A push button typically only makes a connection while you are physically pressing it (momentary action).
