Switch Overview
The Preco SWM43C is a mechanical back-up alarm switch for mobile and industrial equipment. It activates back-up alarms or related safety circuits when position or movement changes the switch state. The switch is rated at 5A for low-voltage alarm loads.
The contacts are field-configurable as normally open (NO) or normally closed (NC). This allows the switch to integrate with a range of existing alarm control schemes and OEM wiring configurations without requiring additional components. The actuator provides 360-degree mechanical movement, allowing installation in orientations where the trigger direction varies.
The housing is composite and water-resistant, suited for outdoor and vehicle-mounted use where moisture and debris are present. The adjustable slotted mounting brackets allow orientation and motion tuning during installation. The switch is CSA approved and UL recognized. It is manufactured in the USA.
