Why wouldn't you? It looks like a slider toggle, not a checkbox.
what is a "slider toggle"? sliders should be used for ranges of values. checkbox for toggling values. we could argue it's unfortunate that iOS(?) decided to start making their "checkboxes" look a little like sliders, but they still only toggle values thus you don't slide them. in any case, i get where you're coming from. using mousedown instead of click or up maybe kind of solves both use cases?
"Checkboxes" that look like little sliders usually are good UI because they avoid this confusion, "is the control showing me the current state or the option to change to the desired state?" For whatever reason, toggle switches like this better convey that they're displaying the current state before you touch them.
