First Inertia Switch Vehicle crash sensor, 8-14G

These switches are designed to automatically trigger in the event of an impact. They are used in production vehicles to cut off the fuel pump in the event of an accident, but are used in EVs to open the vehicle\'s contactor(s), to automatically shut down the traction circuit and isolate the battery pack(s) in the event of an accident. To install, simply connect the Normally Closed contacts between your ignition line and your contactor(s). The switch should be mounted rigidly to the vehicle\'s frame for correct triggering, and in a vertical orientation (i.e red end up) to ensure 360 degree range of operation. The appropriate 3-pin AMP connector is included. A small price to pay for added safety - every EV should have one! Weight: 60 g
