The technology relates to techniques for an electromagnetic inertial switch. An electromagnetic inertial switch can include an electrically conductive and magnetic mass located within a cavity, where portions of the cavity are electrically conductive and are electrically coupled to terminals of the electromagnetic inertial switch. A first magnetic field can be configured to apply a first force on the mass to attract the mass towards a first location, and a second magnetic field can be configured to apply a second force on the mass to attract the mass towards a second location. The electromagnetic inertial switch can be in a first electrical state when the mass is in the first location, and in response to an acceleration event greater than a threshold acceleration, the mass can move to the second location, thereby changing the electromagnetic inertial switch to a second electrical state.
