Why you’ll love it

You get a compact, robust momentary switch that is easy to install and simple to wire. When you press the button, it makes a momentary contact (1NO) and returns to its resting state when you release, making it ideal for signals, indicators, start/stop functions, and doorbells. The device is rated to carry up to 2A across multiple voltages including 12V, 24V, 125V and 250V. This means you can power small control circuits, alarms, and indicators with confidence, without overtaxing the switch.
