Overview: The Series 76-97 push button switches are designed for robust applications, offering a wide temperature range from -40°C to +105°C and panel sealing for protection against immersion. They are available in both momentary and maintained modes, with a brightly colored switch indicator for easy mode recognition.
Features: The switches feature PCB terminals, gold contacts, and are available in 2 poles with various color options. They support surface or sublimation legend printing.
Mechanical Specifications: The switches have a travel distance of 3.5 mm, a nominal life of 2 million cycles for momentary mode and 100,000 cycles for latched mode, with an operating force of 12N. The maximum panel thickness is 6 mm.
Electrical Specifications: The dielectric strength is 1000V RMS, insulation resistance is 1GΩ, and initial contact resistance is 25mΩ. The maximum current rating is 10A resistive at 250V a.c.
Environmental and Physical Specifications: The switches have an ingress protection rating of IP67, can withstand shock up to 50g, and operate within a temperature range of -40°C to +105°C. The body and actuator materials are PBT, with fine silver contacts and terminals plated with bright acid tin and a nickel flash undercoat.
Applications: Suitable for military environments, robust industrial settings, mining, petrochemical industries, process control, and material handling.
Ordering Information: The switches are available in various button styles, actions, terminations, and color combinations. Specific ordering codes are provided for different configurations.
Panel Mounting and Construction: The switches mount into panels up to 6mm thick, with front panel sealing achieved using a sealing washer. They are secured with a lock nut tightened to a torque of 1.5Nm to 2.85Nm. The standard mounting diameter is 22.5mm with a double 'D' flat to prevent rotation.
Multi-Pole Information: A non-standard option for 2 poles is available, which must be fitted separately after mounting the switch body.
