20 May 2018 Question by: Rapid Customer | Product code: 79-0100
Q. Does this switch have continuous rotation? If not, is there any other model that does?
A. Hi Michele, thank you for your question. This is a 12 way rotary switch which has a stop washer under the nut to select less than 12 positions without this inserted it will rotate.


29 January 2014 Question by: Rapid Customer | Product code: 79-0100
Q. Could this be used to turn a circuit on and off? I only want to use the first click (off) and the last click (on). I don't want to use a switch as the design is symmetrical with the volume control knob.
A. Hi, thank you for your question. You can move the end stop so end of movement one way is "off" and next click is "on" and then stop. This is achieved by positioning the limiting collar under the nut and washer.


22 June 2013 Question by: Rapid Customer | Product code: 79-0100
Q. Is this switch suitable for dimming the 12 volt lighting on a model railway please? The lights are NOT led, but conventional.
A. Hi Terry. Thank you for your question. This is more a change over switch - it would only switch lights on and off, it has no way of dimming the lights. A potentiometer would be suitable for light dimming, something like 65-0715 would be more suitable for this application.


18 April 2013 Question by: Rapid Customer | Product code: 79-0100
Q. how to select no ofpoles if I need switch to connectto 4 circuits
A. Hi Monica. Thank you for your question. The configuration can only be done with a 79-0115 or 79-0223.


10 April 2013 Question by: Rapid Customer | Product code: 79-0100
Q. What is the difference from Make-Before-Break and Break-Before-Make?
A. Hi, thank you for your question. These are the terms used in switching, make means the contacts are closed and break is when the contacts are open. So depending on what configuration your circuit requires you have the option to choose which way you want the switch to work.


19 March 2013 Question by: Rapid Customer | Product code: 79-0100
Q. What is the procedure for adjusting the end stop? Regards.
A. Hi Adrian. Thank you for your question. Remove the locking nut and washer - then position the limiting collar as required - then refit the washer and nut.
