Giovenzana PL004003 Switch Contact Block — 1 NO Auxiliary for Pendant & Cam Switches

Italian-Made Contact Block · Screw-Mount · Pkg of 2

The Giovenzana PL004003 is a single-pole normally-open (1 NO) auxiliary contact block designed to snap into the body of a Giovenzana pendant station, cam switch, or foot switch. Giovenzana is a long-established Italian manufacturer of low-voltage control devices, and the PL series is the workhorse contact block used across their PBT / PBF / PSL pendant lines and the QX / QF cam-switch families. The PL004003 is the consumable element that wears with mechanical duty — typically 1–3 million operations — and is the part that gets replaced when a pendant station starts to miss-tick.

At koeed.com we list the PL004003 as a pendant / cam-switch consumable. The block is the part that maintenance stores keep on the shelf for crane controls, hoist pendants, and large-machine operator consoles where the OEM has stopped stocking the assembled switch but the in-service equipment still has years of life left.

Key Specifications

Datasheet Highlights

• Snap-in to the matching pendant / cam-switch body — no drilling, no adapter plate, no rewiring beyond the screw terminals.
• 1 NO configuration covers the most common pendant-button function (e.g. UP, DOWN, FORWARD, REVERSE), and the PL family also offers 1 NC and 2-pole variants for double-throw or safety functions.
• AC-15 rating covers the contactor-coil switching that is the actual load on a pendant — the 10 A thermal current is the design margin, not the operational rating.
• Self-cleaning silver-alloy contacts give reliable operation after long idle periods — important for crane / hoist pendants that may sit for weeks between uses.
• Captive plus-minus screws on the terminals accept ring or fork lugs and standard wiring — no special tooling required.
• Sold in pairs to match the typical pendant button count (e.g. UP/DOWN) and to keep a spare on the shelf.

Typical Applications

• Crane & hoist pendants: UP / DOWN / EAST / WEST buttons on overhead-crane and chain-hoist pendants where the contact block is the consumable part that wears with mechanical duty.
• Cam switches: QX / QF cam switches used as main / auxiliary switches on motors, fans, and pumps in MCC cabinets.
• Foot switches: industrial foot-pedal controls on presses, punches, and welding stations.
• Operator consoles: large-machine operator panels with multiple push-buttons where the contact block is the field-replaceable element.
• Construction & mobile equipment: control pendants on tower cranes, gantry cranes, and concrete pumps where the contact block sees outdoor / weather exposure.
• Service & refurbishment: third-party repair shops that rebuild retired Giovenzana pendants for resale into the secondary market.

Warranty & Authenticity

Each PL004003 is supplied as a brand-new, factory-sealed Giovenzana contact block. KOEED sources from authorised Italian and EU distribution; counterfeits / remarked blocks are rejected at incoming inspection because they cause the missed-tick and welded-contact failures that have caused more than one crane incident. A 12-month limited warranty covers manufacturing defects; KOEED handles return shipping and replacement from EU/US stock at no charge.
