Door clutches are used to disconnect the handle or the padlock device from the switch when they are installed as base mounting or fitted in a large enclosure.

Auxiliary contacts can be used as normally open (NO) or normally closed (NC) contacts.

Key-lock devices are available for several locking programs. For central locking systems refer to the sales office.

Padlock devices can be used to avoid switching if more than one lock is necessary. For padlock devices with door clutch see 'Door clutches and padlock devices with integrated door clutch'

Shaft extensions are used for switches with base mounting to compensate different mounting heights.

The protective cover prevents accidental contact with current-carrying terminals.

Used if a large number of contacts need to be opened simultaneously or the total angular displacement is larger than 30°.

Used to interlock the switch so that the handle can be rotated only when pushed or pulled. Auxiliary contacts can be operated by means of the axial movement of the handle.

The face plates can be engraved or embossed from the front or alternatively from the rear. Face plates in different height are also available. The escutcheon plate frame is black, the face plate brushed aluminium. For switch sizes S0-S3 yellow face plates are also available.

The PFR series is designed to provide protection for machines and machine operators by preventing the equipment (which has been operating) from restarting automatically after a power failure.

This device is used to couple switches into one column. To get an extended amount of auxiliary contacts for example.

This device provides a transparent illuminable handle which can be optionally supplied with a push-pull interlock (S00,S0) and auxiliary contacts (S0).

Ground and/or neutral connecting unit. Also available for KG-switches.

For connecting 2 wires per terminal.

Terminal lugs facilitate the connecting of wires in installations where terminals are not easily accessible.

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.

Two or tree columns can be operated simultaneously. Special programs are available to reinforce the device for heavy duty applications.

The trip indicator is used for switches with spring return positions. It includes a colored indicator to show the last position that the handle has been turned.

Special drives allow switching by other means than a handle.

The device consists of a magnetic system which releases the switch to the trip position at voltage failure or undervoltage (70% nominal voltage).

This device locks the switch in the 'ON'-position. It can be released by the magnetic system or an optional push button for test purposes.

This device is available for square and rectangular plate.

By using this device switches can be operated with depressed button only.

The uni-directional interlock prevents the switch from being operated counterclockwise. The interlock may be either in all positions or in pre-determined positions only.

The motor drive consists of an AC motor with condenser, gear train and Geneva gear. This device allows to be operated from a remote location.

The position indicator shows the location of the switch position, even when the panel door is open and the escutcheon plate is not visible.

The stop and go device prevents a fast switching thru the center 'OFF'-position on 60° double-throw switches. The stop and go device only becomes activated in the center switch position, either in both or one direction.

An interlock between 2 or 3 switch columns permits the operation of one switch only when the other switch or switches are located in a pre-determined switching position. For heavy duty service reinforced devices are available.

Using a slip clutch, two cam shafts can be coupled that the second cam will operate only after the primary cam has been turned over a pre-determined angle.
With a ratchet coupling a part of the switch is only operated when the handle is turned counterclockwise.

The device permits the switch to be turned to the trip position by remote control. The coil is designed for short-time duty requiring an auxiliary contact in the switch.

Only available for KG-switches.

This additional module is for use in Motor Control Center (MCC). It allows for testing and unlocking, with up to 3 additional positions.
