Heavy-Duty 30.5mm Metal Push Buttons, Selector Switches, Contact Blocks, Legend Plates and Pushbutton Enclosures

Item# 10250ED986-4

Heavy-Duty 30.5mm Metal Push Buttons, Selector Switches, Contact Blocks, Legend Plates and Pushbutton Enclosures Heavy-Duty 30.5mm Metal Push Buttons, Selector Switches, Contact Blocks, Legend Plates and Pushbutton Enclosures
The 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 Series of pushbuttons.

The 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.

10250T Series operators have "grounding nibs"?4 metal points on the operator casting designed to bite through most paints and other coatings on metal panels to enhance the ground connection when the operator is securely tightened.

The 10250T pushbutton operators offer front of panel drainage via holes in the operator bushing. Hidden from view by the mounting nut, these holes prevent buildup of liquid inside the operator, which can prevent operation in freezing environments. The holes also provide a route for escaping liquid in high pressure washdowns, effectively relieving pressure from the internal diaphragm seal. This ensures reliable sealing in applications even beyond NEMA 4.
