Working Principle

The MML21HR2BBK is a single-pole, single-throw switch. The switch features a flush (not recessed) button design. This means that when the button is pushed and released, it does not protrude out of the switch enclosure. This helps keep debris, dust, and water out of the switch, thus improving its overall reliability.

The MML21HR2BBK has no built-in power supply and runs on direct current. This type of switch requires a current when the button is pushed and a different current when it is released. The electrical current triggers a mechanical spring loaded mechanism which causes the switch to change position.

The MML21HR2BBK can operate in temperatures ranging from -20°C up to +70°C, and offers a useful life rating of 10 million operations. This pushbutton switch offers 3-pole terminal connection, allowing it to be easily connected to a variety of devices and circuits. It is also UL/cUL listed and offers a wide range of power ratings, 16A, 32A, and 64A.

The MML21HR2BBK is designed to offer superior reliability and performance in a variety of applications. While it might not be the most glamorous of pushbutton switches, it is one of the most reliable and durable available. For customers that need reliability in harsh conditions, this is the right switch for the job.
