Senders & Switches

Engine monitoring senders and switches for warning lamps and shutdown systems. The range covers coolant level probes that open when dry, mechanical and magnetic coolant level switches for side or internal mounting, an electronic probe kit with interface and harness, an adjustable fuel sender with a 150 to 600 mm pivot float arm (10 to 180 Ω) and a five-hole flange, a 100 kPa normally open pressure switch with an M10x1 thread, and a 96 °C normally open temperature switch with a 1/8"-27 NPTF thread.

Switches and probes give an on or off signal, so they drive a warning lamp, a buzzer or a shutdown relay rather than a gauge. Check whether the circuit needs a normally open or normally closed contact, the switch point, and the thread or mounting hole before you order.
