These switches can be used to cycle power to products under test, control status lights, and actuate external power relays and solenoids. The Form C channels are 300V, 1A contacts and can handle up to 50W, and the Form A channels are 30VDC/250VAC, 5A contacts and can handle up to 150W.

Standard 50-pin Dsub connectors allow for use with standard cables, terminal block, or mass interconnect solutions.
