The Wacker Neuson Stop Button Contact is a genuine OEM component designed for the LTS4K, LTS4Y, LTS7K, LTS8K, LTS8L, and LTE4K series light towers. As a direct OEM replacement, this part is manufactured to the exact electrical specifications of the original, ensuring correct contact resistance and reliable circuit actuation every time the stop function is engaged. It fits across a wide range of 50 Hz and 60 Hz configurations — including trailer-mounted and skid-mounted variants — making it a versatile solution for fleets running multiple tower types. Confirm your model number against the fitment list before ordering to ensure a correct match.
Key Features
- OEM-Spec Electrical Contact Rating — Manufactured to the original contact resistance and switching specification, so the stop circuit performs exactly as designed with no signal degradation.
- Direct Plug-In Replacement — Engineered to connect to the existing wiring harness and button housing without modification, streamlining the swap during servicing.
- Broad Light Tower Fitment — Compatible with LTS4K, LTS4Y, LTS7K, LTS8K, LTS8L, and LTE4K series units across both 50 Hz and 60 Hz variants, covering trailer and skid configurations.
- Keeps the Stop Function Responsive — A worn or degraded stop button contact can cause delayed or failed engine shutoff; replacing it restores immediate, positive response when the operator initiates a stop.
- Safety-Critical Electrical Compliance — The stop button is a primary operator safety control. Using a genuine OEM contact ensures the shutdown circuit meets the original design intent and operates within rated electrical parameters.
The stop button contact is the electrical switching element that completes or breaks the ignition or engine-stop circuit when an operator presses the stop button on a light tower control panel. When the contact is in good condition, pressing the button produces an immediate, clean signal that cuts engine power reliably. Over time, repeated switching cycles, vibration, and moisture exposure can cause the contact surface to corrode or wear, resulting in sluggish shutoff response, intermittent operation, or a complete failure of the stop function — a serious safety concern on any powered equipment.
