Circuit Bending Basics: Replacing Button Contacts



Button contacts can be replaced easily if there are other solder points already in the circuit that are directly connected to the two contact points of a button. Two wires can be easily soldered onto the pre-existing solder points.

The two wires, when connected, can then trigger the sound of the toy. Instead of physically connecting these wires, digital pins, relays or transistor-based solutions can be used to trigger the button.


















Button contacts can be also replaced if there are no obvious solder points. Conductive area on the button pads can be scraped back, and then soldering directly onto by adding two wires connected to the button pads.

The two wires, when connected, can then trigger the sound of the toy. Instead of physically connecting these wires, digital pins, relays or transistor-based solutions can be used to trigger the button.
