|
OFF-ON Switch
Two-position switch used to connect or disconnect a variety of inductive loads including: solenoids, handles, valves, magnetic starters and relays.
|
Ammeter Switch
Multi-position switch used to connect one or more phases of an electrical supply to an ammeter, so that the current in each phase can be displayed on one ammeter.
|
Changeover Switch
Two-position switch used in control applications to change between alternate power supplies. This device can typically be used to manually switch power supplies from a primary source to a stand-by/emergency supply in the event of a power outage.
|
Voltmeter Switch
Multi-position switch used to connect two lines of the electrical supply system to a voltmeter so that the voltage between the lines (phase-to-phase or phase-to-neutral) can be displayed on one voltmeter.
|
Star-Delta (Wye-Delta) Switch
Three-position (Off-Wye-Delta) switch used to manually control reduced-voltage motor starting. Operating the switch manually changes the wiring configuration of the motor from a star configuration to delta configuration after the controller operator has determined that the motor is up to operating speed.
|
Step Switch
Multi-position switch used to connect a variety of loads to an electrical supply in a pre-determined logical sequence. A typical application would be temperature control of a heating oven or furnace.
|
Reversing Switch
Three-phase, three-position (Forward-Off-Reverse) switch used to manually control a motor’s direction of rotation. Operating the switch changes the wiring configuration of the motor to operate in the forward or reverse direction.
