A movement detecting device detects movement, or tilt, of a building facilities component, and controls a desired event through an electrical signal without using mercury. The device includes a first housing section and a second housing section held together by a fastener. A ball is disposed between the first and second housing sections within a cavity. A mechanical switch is disposed between the first and second housing sections so that the switch extends into the cavity for contact with the ball when movement of the device exceeds a predetermined angle. A damper arm is included for securing the device to a facilities component to be monitored as desired.
