Pushbutton switches are electromechanical devices that use a pressure mechanism to operate an electrical circuit. The ALFD21111DNUW is a type of pushbutton switch that is suitable for a variety of applications and is adaptable for use in many industries.

The ALFD21111DNUW switch is a Normally-Open Push-to-Make switch. This switch switches an electrical circuit on when a user presses the switch. When the user releases the switch, the circuit is switched off. The switch is “NPN” which means that when the switch is pressed, the N terminal is connected to the P terminal and the electrical current flows through the circuit.

This switch is made of durable materials and is rated for up to 10Amps at 240VAC. It features silver contacts and a black plastic housing, making it resistant to the elements. The switch is also UL/CSA listed which ensures that it meets all industry standards and regulations.

The ALFD21111DNUW switch can be used in a variety of applications including security systems, push buttons, industrial equipment, telephones, and household appliances. This switch is ideal for applications where a single push is needed to activate the circuit. The switch is also easy to install and maintain.

The working principle of the ALFD21111DNUW switch is relatively simple. Once the user pushes down the switch, the pressure activates the contacts on the switch, allowing a current to flow from the N to the P terminal – completing the circuit. When the pressure is removed, the contacts return to their original positions, breaking the circuit.

In addition to the basic pushbutton switch, the ALFD21111DNUW is also available in a range of other options and configurations. Such configurations include momentary switches, latching switches, single pole, double pole and triple pole switches, as well as illuminated switches. These options make the ALFD21111DNUW an ideal choice for almost any application.

Overall, the ALFD21111DNUW pushbutton switch is a highly reliable, durable and cost-effective option for any application. Its operating principle is simple and it is available in a range of different configurations and options to suit any application. With its UL/CSA listing, this switch is sure to provide years of reliable service.
