A system may include an electrical relay and a switch.

An electrical relay comprising having two wettable electrical contacts (118, 120) supporting a conducting liquid (126).

The switch may be coupled to each of the electrical relay and a power transfer device and may be configured to couple the electrical relay to a reference voltage upon engagement of the power transfer device.

A control arrangement (10) is operable to control an electrical relay (12) to supply current.

Static Relay – An electrical relay in which the designed response is developed by electronic, magnetic, optical or other components without mechanical motion.

An electrically relay or residual current device incorporating such an actuator is disclosed.

The moment when the voltage from the electric field producing means is imposed across the breaker contacts is preferably determined by a timer implemented relay.

Rather it activates an electric relay that passes the signal to start the car.

In a programmable power supply used in a semiconductor test apparatus, high-speed switching of a large current in a current rage or an output relay is enabled.

Furthermore a braille array, a valve array, an electrical relay and a mirror array are produced using the micromechanical actuator array.
