Toggle All Switch instance on click

[PeterTough2]

I want to toggle all input checkbox on the page when a particular checkbox with a different class/id is clicked
Here is a function i call when DOM is ready, I want to disable/enable all checkbox on click of an element

function activateSwitchery() {
var elems = Array.prototype.slice.call(document.querySelectorAll('input.state_toggle'));
elems.forEach(function(html) {
var switchery = new Switchery(html, {className:"switchery switchery-small"});
});
}
