It's a toggle switch and it does exactly what it's supposed to. When set to the "on" position things turn on, when set to the "off" position things turn off. The product I received is exactly what is shown in the picture. You can't really tell from the picture, but it comes with a ring around the switch that indicates which position is "on" and which position is "off" but for reference: towards the end where the wires come out is "on" and the other end is "off."The only real issues I have with it is that the actual switch part is really smooth which can make it hard to flip sometimes and it takes a bit of force to actually flip the switch (more force than I was expecting, anyways). However, once you flip the switch there is a solid "click" noise and it stays in place very well. I'm not taking any points off for this since it's really my own personal preference and not an actual issue with the product itself.Overall a great product and a great seller. The package arrived quickly and exactly as advertised.
