FOOT SWITCH SELECTION GUIDE

Foot switches can be used to turn electrical equipment on and off with the foot, freeing the hands to perform other operations or providing ergonomic improvement to a workstation.  Foot switch applications often require specific electrical ratings, enclosures, pedal actions, cables, and other variations.  We also offer customization for manufacturers ó contact us today with your requirements.

Choose the foot switch thatís right for your application:

  • Proper Current and Voltage Rating

  • Enclosure Rating ó Indoor, Outdoor, Hosedown, Etc.

  • Size and Shape ó Large or Small Appearance and Color

  • Pre-Wired or Do-It-Yourself Cabling

  • Single or Multiple Pedal

  • Guard or No Guard

Safety and Selection WARNING: Before selecting or using any foot switch, read the foot switch safety warning.  Only the user can be aware of all conditions and factors present during installation, operation, and maintenance of a foot switch and the surrounding work area.  Therefore, only the user can determine which foot switch(es) and which point-of-operation safeguards are required for a particular application or work station.  Review OSHA and other regulations before selecting or installing any foot switch.  Safety options can include guards to protect against accidental activation, anti-trip safety latches (G-Series only), enclosures ratings, and front access gates.

Foot Switch Pedal Action

There are two main types of pedal action: momentary and maintained.

1) Momentary Action - Press and hold to turn on, release to turn off (like a car horn).  The user must continue to hold the pedal down to keep it on.  As soon as the user lifts his or her foot, the unit will turn off. 

2) Maintained Action - Press once to turn on, press again to turn off (like a light switch).  The unit will stay on until the user presses forward a latch inside the hood on the G-Series "-MA" models or presses the other end of the pedal on the S420-Series to release it back to the "off" position.  The F300 also offers push on / push off maintained action.

Additionally, the G-Series is available with the Anti-Trip Safety Feature (-AT models).  The user must press forward a safety latch inside the hood before pressing down on the lever to turn it on.  These units then have a momentary action; the user must keep the pedal pressed down in order to keep it on.

Electrical Circuitry and Contacts

Typically, foot switches contain SPDT contacts that are wired "normally open."  That is, the switch is open, or "off," when not in use.  Choosing the proper current and voltage rating for a foot switch application will depend on the circuit the foot switch is attached to.  The amount of electrical current that will flow through the circuit will determine the amperage rating required for the foot switch.  Consult a certified electrician with any questions to determine the amperage, voltage, and power requirements for your application.

  • S-Series, B-Series, and F-Series foot switches are sometimes shipped with cables attached (depending on the model).  Units with cables typically have SPDT contacts that are wired normally open.

  • G-Series foot switches can have several different switch circuit optinos and are not typically shipped with cables.

Foot switches with cables (S-Series, B-Series, and F-Series)

Models with Piggyback Plug

Examples:  S100-1501, S400-1501, B800-1501, F200-1501

Circuit: SPDT

Comes pre-wired normally open (in "off" position until pressed).

  Plug into any standard 120-volt 3-pronged wall outlet (United States only), and then plug your device into the back end of the plug.  When you press the foot switch, the device will turn on.  
(model S100-1501)

Models with Leads

Examples: S100-1502, S400-1502, B800-1502, F200-1502

Circuit: SPDT

Comes pre-wired normally open (in "off" position until pressed).

Amperage Rating

The amount of electrical current that will flow through the circuit will determine the amperage rating required for the foot switch.  The amperage rating is important so the switch and wiring can handle the current that will flow through the circuit.  Consult a certified electrician to determine amperage, voltage, and other requirements for your application.  Follow all local and national electrical safety regulations.

G-Series Foot Switches - Features and Variations

G-Series foot switches include either one or two SPDT switches.  G500 models have one switch, and G502 models have two switches.

The switch activation points are adjustable for some G-Series foot switches.  To increase pedal travel before the switch is activated, turn the Adjustment Screw clockwise.  To decrease travel before the switch is activated, turn the Adjustment Screw counter-clockwise.

For models with two switches (G502 models), both switches can be independently adjusted.  If both switches are set to go off at the same time, the unit will have DPDT circuitry.  The switches can also be set so one goes off before the other.

Two-stage models (models ending in "-2S") have an additional spring mechanism that provides a distinct tactile feel between the activation of each switch.  The user will feel an additional force after activating the first switch when pressing the pedal down halfway; the user can then either hold at that position or continue pressing the pedal down to activate the second switch.
