Overview: The Series 76-59 is a range of vandal-resistant push-button switches designed for rugged applications. These switches are machined from stainless steel, ensuring durability and resistance to harsh environments. They are panel-sealed to IP67 standards, making them dust-tight and protected against immersion in water up to 1 meter.

Features: The switches feature a non-rotating button, gold contacts, and solder terminals. They are available with PCB terminals, illumination options, and engraving, and can be tailored to specific requirements.

Mechanical Specifications: The switches require an operating force of 3N and support panel thicknesses from 1.5 mm to 8 mm. They have a body diameter with an M19 thread and a panel cut-out diameter of 19.25 mm. The switches are designed for a minimum life of 1,000,000 cycles with a travel distance of 2.3 mm.

Electrical Specifications: The dielectric strength is rated at 1KV AC for 1 minute, with an insulation resistance of 1GΩ at 500V DC. The initial contact resistance is 50mΩ. The electrical load ratings are 400mA at 32 VAC, 100mA at 50 VDC, and 125mA at 125 VAC, with a life expectancy of 500,000 cycles at maximum load and 70°C.

Environmental and Physical Specifications: The switches operate within a temperature range of -30°C to +105°C. The body and actuator materials are stainless steel, while the contact material is gold-plated nickel. The terminal material is brass with a bright acid tin plate and nickel flash undercoat.

Applications: These switches are suitable for various applications, including process control, railway carriage equipment, external security door controls, elevators, fishing vessels, crane gantry equipment, earth-moving equipment, upper deck yachting equipment, and medical instrumentation.

Mounting and Construction: The switches are mounted from the front into a 19.25 mm diameter panel cut-out. Panel sealing is achieved with a sealer washer, and the switch is secured with a lock-nut from the rear.
