Q: Is the pump or foot switch locking or momentary action?
A: Both switches are momentary.
Q: What is the nominal voltage for Trombetta's pump and foot switch?
A: Trombetta's pump and foot switches are rated up to 24 volts.
Q: Are these quiet click-free momentary switches or do you hear a click when they are depressed?
A: You hear a click.
Q: What is the maximum sustained duty cycle for the pump switch?
A: The duty cycle is 50%. The formula is: On time/(On time + Off time).
Q: What is the maximum sustained duty cycle for the foot switch?
A: The duty cycle is 25%. The formula is: On time/(On time + Off time).
Q: What is the maximum continuous on time for the pump switch?
A: 120 seconds
Q: What is the maximum continuous on time for the foot switch?
A: 20 seconds
Q: What is the peak inrush current capability for the pump switch?
A: 500 amps, based on a rise of > 3 milliseconds to 80% of peak inrush with linear decay to carry current in < .1 seconds.
Q: What is the peak inrush current capability for the foot switch?
A: 400 amps, based on a rise of > 3 milliseconds to 80% of peak inrush with linear decay to carry current in < .1 seconds.
Q: What is the current carrying capability for the pump switch?
A: 200 amps, based on maximum duty cycle of 50%.
Q: What is the current carrying capability for the foot switch?
A: 80 amps, based on maximum duty cycle of 50%.
Q: What is a 3rd generation key switch?
A: Contacts on 1st and 2nd generation switches use a wiping action when moving from one position to the next. Trombettas unique third generation key switch doesnt utilize a wiping action. The key switch is designed with individual contact points that cam open and close with one switching point for each circuit controlled.
Q: What is the electrical rating?
A: The electrical rating for each model is 20 amps.
Q: What is the electrical life cycles (inductive)?
A: 20,000 cycles.
Q: What is the operating temperature?
A: They are designed for temperatures of -30°C to 70°C.
Q: What is the Pin Configuration for Trombetta's Key Switch?
A: The 3 position model utilizes a 5 pin configuration that mates with AMP/Tyco connector. The 4 position model utilizes a 7 pin configuration that mates with AMP/Tyco connector.
