Named after Sir Walter Scott’s first novel, Paddle Steamer Waverley was built on the Clyde in 1947 – to replace the 1899 Waverley that sunk off Dunkirk during active war service in 1940.
Celebrating 40 years’ sailing in preservation, Waverley has been operated by a charity since 1975 and preserved as a heritage asset for the benefit of communities around the UK. A major £7m two-stage rebuild was undertaken in winters of 1999/2000 and 2002/2003 in Great Yarmouth with the support of the National Heritage Lottery Fund, whereby the huge task of restoration was carried out to get it back to its’ original condition, whilst complying with the newer regulations.
The main engine telegraph and its bell are located both in the engine room and on the navigation bridge. A responsible officer from each of the departments handles the telegraph from these locations.
There became a need for an additional telegraph for use in the event of a problem with the main telegraph, with the parts sourced from various locations to keep the visual authenticity. This in turn created a need for a one-off switch for the selection by the bridge officer to indicate the direction and speed required of the main engine. This was kindly donated by Kraus & Naimer Ltd based in Newbury. The switch itself was made to the specification of the Chief Engineer, a bespoke 12 position multiway switch.
Almost all of Waverley’s machinery including the impressive 2100 IHP main engine, steering and all the main pumps are powered by steam from her two massive oil fired boilers.
The Waverley continues to be maintained in excellent condition with its’ towering funnels, timber decks, gleaming varnish and brass. Sustenance of this relies on the goodwill of businesses to keep costs to a minimum and in turn giving the wonderful opportunity to sail on a paddle steamer to as many people as possible.
Schurter announces its latest IEC appliance outlet with insulation displacement contact (IDC) terminals, the 4710. The new outlet provides increased power ratings over the popular 6610 series for heavier duty PDU applications.
The 4710 is a J style outlet according to IEC 60320, rated 20 A @ 250 VAC by UL/CSA and 16 A @ 250 VAC by ENEC. The lower current version, 6610 series, is a style F outlet, rated 15 A @ 250 VAC and 10 A @ 250 VAC respectively. The 4710 provides IDC terminals for 10 AWG / 6.0 mm2 in addition to 12 AWG / 4.0 mm2, which is the standard wire size for the 6610. The new wire option allows for larger diameter wire for the 4710's increased power capabilities. The Snap-in outlets fit panels with a thickness between 0.8 mm and 3 mm.
The 4710 and 6610 outlets are qualified for use in applications designed to IEC/EN 60950. Ideal for use in power distribution units, and other equipment where multiple outlets are banked in series, these IDC outlets allow wires to be bussed across the terminals, thereby connecting common terminals all at once and significantly reducing labor costs. The IDC terminals are arranged either along or across the connector pin axis for a horizontal or vertical mounting orientation. Wires are pressed into place with the protective back cover or with a tool. Versions with combination IDC and a quick-connect or solder terminal, for separate wiring of the line connection, are also available.
The outlets are offered with light pipe options for status indication. They also mate with V-Lock latching cordsets designed to prevent unintentional disconnection from the power. Approvals include cURus, ENEC and CCC.

Schurter is expanding its PSE, piezo metal switch and MCS 30, mechanical metal switch series, with new illumination possibilities powered by variable input voltages. Based on the used RGB color technology, it’s now possible to indicate up to seven illumination color options with just one switch. The variable power supply offers a homogenous and brilliant illumination within a voltage range of 5 to 28 VDC.
The new multicolor illumination of the PSE and MCS 30 series is made easy using convenient color-coded wires in each of the illumination colors. Each color is given a specific voltage between 5 to 28 VDC. The constant brightness intensity is maintained regardless of applied voltage. The standard version is offered in red, green, and blue. Additional color options include yellow, cyan, magenta and white, which can be made through additive color mixing. As soon as the 2 or 3 wires are supplied with the applied voltage at the same time, the result is a mixed color. The traffic light colors of red, green and yellow (RGY) for status indication are also available as a standard version. No additive color mixing is required to produce the color yellow.
The new RGB multicolor illumination option greatly expands the application range of the PSE and MCS 30 button style switches. The PSE is available in 22 / 24 / 27 / 30 mm diameters; the MCS 30 is available with a 30 mm diameter. The PSE has an IP69K ingress protection rating. It has no moving actuator and is thus absolutely impervious to any leaks or accumulation of dirt underneath or around the switch surface. This technology is ideal for hygiene-related applications such as medical equipment, food processing equipment and outdoor applications subject to vandalism such as ticketing machines.
The MCS 30 is an alternative to the highly robust, solid state PSE. It is also designed for demanding applications, although it uses a tactile switch that provides a clear haptic feedback. It has a lifetime rating of one million actuations, as opposed to the PSE's 20 million operations. The switch contacts are sealed from the front and rated IP65.
Technical Data:
