The EATON Cutler-Hammer 10250T 30.5 mm pushbutton line features a zinc die cast construction with chrome-plated housing and mounting nut.
The same durable construction is also available with the corrosive resistant E34 line of pushbuttons.
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.
Eaton's Cutler-Hammer® contact blocks feature enclosed silver contacts with pointed "reliability nibs" for reliable performance from logic level up to 600V. To ensure reliable switching, nibs bite through oxide which can form on silver contacts, eliminating the need for expensive logic level blocks for most applications.
Reliability nibs improve performance in dry circuit, corrosive, fine dust and other contaminated atmospheres. Under normal environmental conditions, the minimum operational voltage is 5V and the minimum operational current is 1 mA, AC/DC. For operation under a wider range of environmental conditions, logic level contact blocks with inert palladium tipped contacts are recommended.
