A pushbutton switch is a type of switch designed to be connected to a set of contacts that can open or close an electronic circuit. Pushbutton switches are widely used in a variety of applications, from simple momentary-contact switches for on/off control, to advanced controls that require the user to push and hold the switch for continuous operation. The ALFD21111DNUR is a pushbutton switch designed specifically for applications such as lighting and equipment control, as well as access control and industrial instrumentation.

The ALFD21111DNUR is a single-pole double throw (SPDT) pushbutton switch that operates on up to 6A at 260VAC. The ALFD21111DNUR is an illuminated pushbutton, making it suitable for applications where visibility is a must. The switch is illuminated with a 12VAC/DC incandescent or an LED bulb. The switch can be configured with a normally open, normally closed, or a momentary configuration. The momentary configuration works by using a spring-loaded plunger that when pressed returns to the home position, meaning it can be used for single push acts.

The ALFD21111DNUR is designed for use in applications where reliable and repeatable actuation is required. The switch has a precision die-cast metal housing that is resistant to vibration and seals the switch contacts from any contaminants. The metal housing also acts as a heat sink to extend the life of the switch. The metal housing has a threaded mounting nut that mates with a threaded opening in an enclosure. The switch’s long-term mechanical and electrical reliability is further assured by gold-plated contacts and a 10 million electrical cycle rating.

The ALFD21111DNUR is a rugged, reliable, and versatile switch, making it well-suited for many applications. It can be used for light and equipment control, security access control, industrial instrumentation, and even momentary-contact circuits. Highly visible lighting makes it well-suited for applications where visibility is a must. And the metal housing ensures reliable performance in even the most demanding environment.
