The Swisstac series Keylock Switch can be altered very simply any number of times and afterwards added to, modified or adapted. This highly modular concept means that only a few subassemblies need to be stocked, so shortening lead times, simplifying inventory control. All the terminals are arranged at one level, clearly laid out and fully accessible even when in close-packed arrays. Three colours help to make wiring up easier. Every switch is tested after assembly. Electrical performance and useful life are governed by the contact element. Front and intermediate section are designed for the maximum useful life of the contact element. These determine the manner of protecting the switch against outside influences. It can be mechanically combined in many ways to form switch interlock systems in rows of up to 20 switches. So complicated protective and relay interlocks are unnecessary. Individual and irregular spacing between the switches of an array are no problem either.

• Front section - Man/switch interface and status indicator
• Intermediate section - Latching/pulse facility, lamp holder, latch function select
• Terminal block - For up to five contact elements
• Thermoplastic actuator with fire prevention characteristic
