The Wacker Neuson Contact Block is a genuine OEM component designed for the LTN5Y and LTN4Y series light towers, including the LTN5Yp, LTN5Yp HD, LTN5Y SA, LTN5Ypa, LTN5Ypk, LTN4Y, LTN4Y SA, and LTN4Y 120V/60Hz models. Sourced directly from Wacker Neuson, this part meets the original build specification — no guesswork on fit or function. It covers an extensive range of LTN light tower configurations, making it a straightforward solution whether you're servicing a standard unit or a region-specific variant. Keep a verified OEM part number on hand to get your light tower back in service fast.
Key Features
- Genuine OEM Electrical Integrity — Manufactured by Wacker Neuson to match the original contact rating and switching specification of the LTN series light tower electrical system.
- Direct Drop-In Replacement — Engineered to connect and seat exactly as the original, with no adaptation needed to the existing wiring harness or mounting position.
- Broad LTN Series Coverage — Confirmed fit across LTN5Y and LTN4Y model families, including HD, SA, CH, UK, and 60Hz variants, covering both 50Hz and 60Hz configurations.
- Protects Electrical Circuit Continuity — A properly functioning contact block maintains clean, consistent switching action; a worn or pitted contact block causes intermittent faults, voltage drops, and unreliable operation of downstream electrical loads.
- Electrical Safety Compliance — As a switching and current-carrying component in a tower-mounted lighting circuit, using the correct OEM-rated contact block is essential to maintaining safe, compliant operation of the electrical control system.
A contact block is the current-carrying core of a push-button or selector switch assembly — it's the part that physically opens and closes the electrical circuit when the operator presses a control. In a light tower like the LTN series, contact blocks are used in the control panel to switch power to the lighting load and other circuits. When a contact block wears out or its internal contacts become pitted or corroded, the switch may fail to make a solid connection, resulting in flickering lights, unresponsive controls, or a complete loss of function in that circuit. Replacing a failed contact block restores full, dependable switching action and keeps the control panel operating as intended.
