Product catalog summary
Overview: The Series 59 Maintained switches are designed for robust industrial applications, featuring a non-rotating button and a panel sealed to IP67 standards. These switches are suitable for a wide range of environments, including process control, railway equipment, and military applications.
Specifications:
  • Mechanical: Operating force is 3N, with a panel thickness range of 1.5 mm to 3 mm. The body diameter is M14 thread, and the switch has a minimum life of 100,000 cycles with a travel of 3.1 mm nominal.
  • Electrical: Dielectric strength is 1KV AC for 1 minute, with an insulation resistance of 1GΩ @500V d.c. The contact resistance is initially 50mΩ. The electrical load current rating is 400mA @ 32 VAC resistive, 100mA @ 50 VDC resistive, and 125mA @ 125 VAC resistive.
  • Environmental and Physical: The switch is rated for an operating temperature range of -40°C to +105°C. The body and actuator materials are PBT, with gold-plated nickel contacts and gold-plated brass terminals.
Features: The switch includes PCB terminals and offers surface or sublimation legend printing. It is tailored to suit specific requirements and is available in various button colors including black, red, green, white, yellow, blue, and orange.
Mounting and Construction: The switch mounts from the front into a double ‘D’ panel cut-out. Panel sealing is achieved with a sealing washer and a lock-nut, requiring a tightening torque of 0.55Nm - 0.65Nm.
Ingress Protection: The switch is protected against dust and the effects of immersion up to 1 meter, conforming to IP67 standards.
Ordering Information: For further details, contact ITW Switches, a division of ITW Limited, located in Portsmouth, England. Contact details include phone, fax, and email, with additional information available on their website.
