Eaton's 10250T line of 30.5 mm pushbuttons features a heavy-duty zinc die cast construction. Reliability nibs improve contact reliability even under dry circuit and fine dust conditions. In addition, drainage holes prevent the buildup of liquid inside the operator, which can prevent operation in freezing environments.
