Abstract

A switch including a sealed housing; a magnetic sensor; and a control element configured to modify a control parameter for the switch in response to a signal from the sensor. In some aspects, the magnetic sensor is arranged to produce the signal in response to a magnetic field generated outside of the housing. In some aspects, the switch is a vibration switch, or is selected from the group consisting of a flow switch, a level switch, a temperature switch, a pressure switch, a proximity switch, and a velocity switch. In some aspects, the switch includes a two-wire configuration and first and second output pins arranged to provide an output signal for the switch and to receive a signal for programming the switch. In some aspects, the switch includes a two-wire configuration and a current-control element arranged to reduce current output for the switch.
