We offer a large variety of optional extras as e.g. key-operators, padlockable handles, auxiliary contacts or enclosures. This allows us to meet the requirement of the world market.
One or more optional extras may be used in combination with any one switch provided they are of the same switch size. In some cases, for technical strength or esthetic reason, it may be desirable that a switch be combined with an optional feature of the next larger switch size.
The electro-mechanical interlock locks the switch in any switching position. The interlock device is operated by energizing or de-energizing the electro-mechanical system. Adding auxiliary contacts to the switch permits the device to be operated in pre-determined positions.
Isolating enclosures are available either as a highly UV-resistant design as well as for applications in an aggressive environment, such as oil, chemical substances, and grease. All variants are offered with cover coupling with or without cover interlock, strong durable plastic and increased wiring space.
