Internationally, contacts are rated by IEC(International Electrotechnical Commission) standards. Bymatching the contact rating to the load requirements, aproper contact block can be selected. Typically, push Buttoncontact selection includes the following factors;Voltage/Amperage Requirements, Type of Load contacts selected must be capable of handling thevoltage and current to be switched.

5 Control circuit loads aretypically called pilot duty loads. The load being switchedcan be a relay, contactor, or similar device that activates a"power"power circuit . Pilot Duty devices should not be used toswitch horsepower or lighting loads unless they arespecifically rated to do state applications such as those with programmablecontrollers may require contacts that are able to switch lowcurrent and low voltage resistive loads. Logic reed typecontacts provide reliable switching of solid state loads withminimum contact or hazardous location environments mayrequire the use of sealed switch type contacts. Applicablecodes should always be Wiring Diagramsfor push Button Control StationsPilot Light SelectionPilot Light selection is based on the following factors;Voltage, Lamp Requirements, Environment, and voltage of a pilot light must match the voltage both AC and DC voltage sources are available, AC voltageis recommended because it typically extends lamp life onincandescent units.

6 When using an AC source of 120 Voltsor higher, a transformer type pilot light can also increaselamp of the type of lamp can also affect lamp life. Thereare three types of lamps commonly used in pilot lights;incandescent, neon, and LED (Light Emitting Diode).Incandescent lamps have the shortest lamp life and aresusceptible to damage from shock and lamps with lower voltages have thickerfilaments and burn cooler, plus are more durable. Neonlamps provide longer lamp life, but have slightly reducedillumination. LED lamps provide the longest lamp life andare the least susceptible to damage from shock requirements are also important whenselecting a lamp. Depending on the color, an incandescelamp can provide brighter illumination when comparedwith a neon or LED of the unit in terms of initial expense should also be4addressed.

7 Although it may be cost effective to initiallyinstall a device with a full voltage incandescent lamp, atransformer type, LED or neon unit can reduce downtimecosts through increased lamp more information on Pilot Light selection, refer toAllen-Bradley, Milwaukee, otherwise specified, the circuits provideProtectionundervoltage protection or "three wire control. In theevent of power failure, these circuits are designed to protectagainst automatic restarting when the power returns. Thistype of protection should be used where accidents or damagemight result from unexpected circuits using undervoltage release or "two wire Releasecontrol are noted in the Table of Contents. With any type ofcontrol, the motor starts automatically after a power , these circuits involve automatic pilot devicessuch as thermostats, float switches, Wiring DiagramsFor push Button Control Stations5 Explanation ofSymbolsMomentary Contact push Button -Auxiliary Contacts-Operate whenOperating Coil of Contactor:Depressing Button opens andparent switch does.
