Product Overview
Preco SWM43C Back-Up Alarm Safety Switch Kit – Unused New Old Stock
The Preco SWM43C is a mechanical back-up alarm switch built for mobile and industrial equipment where movement must trigger a reliable safety signal. As a water-resistant, USA-made switch with full 360 degree mechanical movement, it provides a simple and dependable way to activate back-up alarms or related safety circuits on vehicles and machinery. This kit format supports field installation and legacy system maintenance without requiring proprietary hardware.
Preco has long supplied safety signaling components to equipment manufacturers across construction, material handling, and fleet operations. The SWM43C follows that tradition as a composite-bodied variant of the SWM43 family, offering a rugged housing with flexible wiring options for normally open or normally closed configurations. Its straightforward mechanical design allows integration with linkages, levers, or position-driven mechanisms that need to energize an alarm during defined motion.
Product Condition
Unused, new old stock. Kept in original manufacturer packaging and preserved in clean, stable condition. No signs of prior installation.
Product Overview
The SWM43C is rated at 5 A and supports low-voltage alarm loads common to back-up alarms and similar safety devices.
