Specifications

Restore dependable electrical control to compatible powered tarp systems with the US Tarp 1133440 EZ Switch Relay. This replacement reversing relay allows the control switch to operate the tarp motor in opposite directions, supporting tarp deployment and retraction.

The relay features a six-terminal connection arrangement and a hermetically sealed housing designed to protect internal electrical components from moisture and environmental exposure. Its weather-resistant construction makes it suitable for demanding commercial truck and trailer applications.
