Switch Specifications

 

Switch specifications to consider when searching for foot switches include:

 

  • Pedals - Foot switches can have one, two, or three pedals. 
  • Switch or Actuation Method - Choices for switch or actuation method include:
    • Snap action - In a snap action switch the action speed of the switch contact is independent of the actuator speed.
    • Slow action - In a slow action switch the contact points move at a speed proportional to the activating motion and are typically used for lower voltage applications.
    • Air switch - An air switch uses a foot actuated air bulb for actuation to a remote switch.
    • Potentiometer - Some switches contain an integral potentiometer.How to Select Foot Switches

    • Maintained contact
    • Momentary contact
    • Single stage
    • Two stage
    • Three stage
    • Mechanical interlock
    • Variable 

Electrical Switch Specifications

 

Electrical switch specifications to consider when searching for foot switches include:

 

  • Pole and Throw - Pole and throw specification choices include:
    • Single pole, single throw (SPST)
    • Single pole, double throw (SPDT)
    • Double pole, single throw (DPST)
    • Double pole, double throw (DPDT)
  • Configuration - Switch configuration can be normally open or normally closed.
  • Contact Style - The contact style can be single break, double break, shorting, or non-shorting.
  • Maximum Current - The maximum current is the maximum nominal, or nameplate current capacity of a device.
  • Maximum AC & DC Voltage - The maximum AC and DC voltage capabilities are also important to consider.


Physical Specifications
