Q. What current can the contacts take using 12 volt DC power.
I know it is 300mA at 125 volts AC - but I need to know the maximum DC current at 12 Volts.
A. Hi Madeline, thank you for your question. According the manufacturer, these solder tag rotary switches can take 400mA at 12VDC.

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.

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.

Q. Do these come with control knobs? And if not, do you sell them?
A. Hi Nick. Thank you for your question. We sell the tops for these as they are not supplied with the unit. 32-0290 would be suitable for this rotary switch - bigger sizes are available.

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.

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.

Q. will this suit a spec for 1 pole 4 way I cannot see how it is wired. I would assume 2 poles can be left unwired but I have been told never to assume, you know the old saying? about asses.
A. Hi Anthony. Thank you for your question. You can do that - use one pole out of the 3 and follow that pole in the 4 positions. The other 2 poles can be left unused.
05 February 2013 Question by: Rapid Customer
Q. Hi there. What's the difference between make before break & break before make?
I need some rotary switches where each pole simply moves from one output to another (or another ...).
A. Hi Antony. Thank you for your question. When used as an audio selector the make before break can prevent a click on the speakers as the selector is changed. This means that the previous circuit is maintained briefly connecting the 2 as you change it. For all other applications the break before make should be used. This type disconnects the previous circuit completely before making the new connection.

Q. Do you have any knob caps in your catalogue range that suits?
Spec mentions 9.8mm diameter mounting bush. I presume it's refering to the stem, but can't seem to find any caps that fits, spindle or D type.

Q. I need to switch a max of 2.0 amps at 20V for model railway control. Would these switches handle this current - if not what in your range would?
Thank you, Chris
A. Thanks for your enquiry Chris. These switches will not handle 2amps, 300ma on the contacts are the maximum. We have no range of rotary switches with this sort of current available however, we have some switches (order code 75-0082) which you may find suitable.

Q. which on of these rotary switches have 45 degree and 30 degree turn index.
79-0100
790105
79-0110
A. Hi John, thanks for your question. None of the switches have anything more that 20 degrees of rotation.

Q. Are these make before break ?
The wording "Available in Make Before Break Version" makes me think its another option.
A. Hi Mike, thanks for your question. 79-0110 are make before break, there are others in the range which are break b4 make.
