Need a secure key-operated switch for a project? This CCL momentary key switch is perfect for access control panels, machinery, security boxes, or automotive applications. It's a 2-position, 1-circuit switch with a spring return—meaning you turn the key to activate it, and it springs back to the off position when you let go. It uses screw terminals for solid wire connections. UL listed for safety. Part number S203A-2001. Brand new in packaging. Great when you want something that only works while the key is held in the 'on' position. A simple, reliable way to add key-controlled power to your setup.
