The AML31FBE4AD Honeywell Push Button Switch has snap-in surface mount. Push-button Switches, also known as biased switches, work on simple electric switch mechanism. Push-button Switches are a type of momentary switch in which the user push-for "on" or push-for "off" to control some aspect of a machine or a process. The buttons are usually made of metal or plastic and deliver instant response.

The AML31FBE4AD Push Button has rectangular pushbutton switch housing with a 28V lamp circuit. The lamp circuit is independent of the switch circuit. It provides alternate action with 2-pole, single throw, normally open, Form X circuit. This Push Button Switch is UL recognized and CSA certified with metric design for fully acceptable quality and safety standards. Potential applications of AML Series push-button switches include manual operations, such as control boards and panels in industrial and test equipment, process control, and medical instrumentation.
