Unwire a light switch
In order to wire this switch as "always on", all three wires should be removed from the switch and bundled together with a wire nut.

The three wires is a bit non-standard and might lead you to believe this is a 3-way switch or some other kind of odd arrangement, but someone has used the stab connector and the screw on the top of this standard switch to tie those two wires together.  If this switch only controls one light then one of the top wires is the power coming in, the other top wire is going on to another switch or outlet, and the bottom single wire is what provides power to your light.

If you wanted the switch to be "always off" the top two wires should be connected with a wire nut and the bottom wire would be capped off.  For always on, bundle all three wires.

To release the wires from the stab connectors, there is a slot that you can fit a small screw driver in to push open the connector.
