Green DS427 12 mm momentary OFFON pushbutton switch. This 1 piece features a 12 mm diameter pushbutton with OFFON momentary action. It is rated for 3 A at 125 VAC and 1.5 A at 250 VAC, making it suitable for general control and signaling tasks in compact panels and electronic projects. The model is listed as DS427 (also DS427). Key benefits Momentary OFFON action: Energizes the circuit only while the button is pressed, returning to OFF when released, which reduces wear and power usage for momentary controls. Clear visibility: Green color provides quick visual identification for onpress functions in control panels or test setups. Compact, 12 mm form factor: Small footprint fits tight panel layouts and hobby projects without compromising performance. Versatile electrical ratings: Supports up to 3 A at 125 VAC and 1.5 A at 250 VAC for a range of low to mediumload applications.
