Push once to turn one side on, push again to turn the other side on! It's basically a push-button toggle switch that connects and disconnects the middle pin from either of the two side switches with every click.

This clicky switch makes a great power switch or mode toggler. We like this switch because it's easy to embed in a seam for easily powering up/off multi-wire wearable and fabric projects. Can reliably handle up to 3A and up to 120VDC. This is a really satisfying switch.
