Pushbutton switches, often referred to as momentary contact switches, are devices with two states – either open or closed – that are activated when a button or lever is pressed or released. The ABD311N-B is one such switch, offering extended life (over one million cycles), reliable performance and a high-degree of water-resistance (

The ABD311N-B can be used in a variety of applications, including those related to power management, lighting controls and HVAC systems. It is also commonly used in audio visual and amplifier systems, as well as security systems. Essentially, it is an ideal solution for any application requiring a reliable, durable switch.

The ABD311N-B is a single-pole (SP) normally-open momentary contact switch, which means that when the actuator is pressed, it closes the switch until the actuator is released and then reopens the switch. This “momentary action” allows the switch to be used as a manual override for automatic systems, enabling users to temporarily override a system until it is manually reset.

The ABD311N-B is designed to be mounted on a standard DIN rail and is available in both snap-mount and recessed mounting versions. It has two sizes for the actuator, with short and tall actuators, and is available with two termination options: either screw terminals or flying leads.

The ABD311N-B offers users a high degree of safety, as it is UL and cUL listed, as well as rated for use with 16 AWG (1.5mm²) to 18 AWG (0.75mm²) wire. Its superior operating temperature range (from -40°C to +85°C) ensures reliable performance even in harsh industrial and outdoor environments.

In addition to its excellent technical specifications, the ABD311N-B is also an aesthetically appealing switch, boasting a sleek and modern design. Its black body and white actuator blend seamlessly into any industrial setting, while its mounting depth is as shallow as 17.5mm.

Overall, the ABD311N-B has all the features necessary for applications that require reliable, durable, and aesthetically pleasing switches. Its superior performance and extended life make it an excellent choice for any pushbutton application.
