• Anatomy of a Switch:
Actuator: Toggle, Pushbutton, Rocker, Lever
Moveable Contacts: Gold, Silver, Nickel
Terminal Types: Metal portion of the switch exterior to body that is
used to connect the switch to an electrical circuit
Screw (standard or Clamp), Solder, Quick Connect, Wire leads, Plug In, Wire Wrap
Switch Education
What is a Switch?
A switch is a device that will either open or close a circuit. The switch will establish a connection
between two or more circuits:
Poles: Number of circuits a switch controls
Throws: Number of conductors to which a switch can complete a circuit
Positions: Number of stops the switch actuator makes
Normally Open (NO)-circuit is open when actuator is in relaxed or normal position
Normally Closed (NC)-circuit is closed when actuator is in relaxed or normal position
Switch Education
• Switch Rating: Maximum electrical load the switch is capable of
handling
• Voltage:
– AC Alternating current (minimum UL requirements)
– Horsepower
– DC –Direct Current (minimum UL requirements)
– Horsepower (for switches designed to control small motor loads)
Switch Education
Contacts:
Gold Flash A plating of gold typically less than 10 millionths thick.
Used only as a barrier to oxidation or corrosion of terminals to
maintain solderability
Gold plating should be used when the switch’s voltage and current
multiple is no greater than 0.4 VA and the voltage is not greater
than 20 VDC or peak AC.
Switch Education
Momentary Vs. Maintained
Single Pole Single Throw SPST (two position)/On-Off:
The is the simplest and most basic circuit. Only one circuit is closed by the switches single pole.
Double-Throw Without Center Off (two position)/On-ON: SPDT
It is seen electrically On-On. The switch has two manual positions and reflects two
independent electrically ON positions. Two circuits can be closed by the switches single pole.
Examples of applications include a selector function, such as 6 or 12V on a battery charger or HiLow on a automobile headlight switch.
Switch Education
Double-Throw with Center Off (three position): Hi-Off-Low:
It has two independent ON switches, it can be considered On-Off or Hi-Off-Lo Circuit for
the exhaust fan in a kitchen range hood.
Double-Throw Momentary Action with Center Off (three position):
Momentary or non maintained. Momentary is electrically On or Off, generally has spring loading.
Examples are UP-Down for projector screens, tailgate windows, and forward/reverse for electric
drills and screw drivers
