DESCRIPTION

The 76PSB09T is a 9-position thru-hole DIP switch from Grayhill's Series 76, featuring a piano-key actuator style with sealed base construction where up position indicates off (open) state. The switch employs spring and ball contact technology with brass gold-plated shorting members and copper alloy gold-plated base contacts, ensuring reliable electrical performance. It has a length of 0.980 inches (24.9 mm) and operates over a temperature range of -40°C to +85°C with a mechanical life rating of 2,000 operations per switch position. The switch supports make-and-break current ratings of 1 mA at 5 Vdc, 50 mA at 30 Vdc, or 150 mA at 30 Vdc, with initial contact resistance of =30 mO and a current carry rating of 5 A maximum. This sealed design is ideal for machine soldering, heavy cleaning applications, and environments requiring protection against moisture and contamination.
