Sarah, I believe the Airequipt Jr has a cover interlock switch, may be your unit has a defective switch that is "on" for white light all the time. A handy person may find a way to replace the switch, or perhaps even fix the switch.
Answering your question, any "in line" switch, like those used for table lamps, could be used. Your local home improvement center could provide you with the switch and advice on its installation. Make sure you tell them how the power cord looks like. It should not be a problem installing this switch.....heck, even Martha can do it, I saw her installing a $2 switch on an "inexpensive" Tiffany lamp, I think it was show # 666!! An even easier/better solution is just to plug the Airequipt cord to an enlarger timer, this way you have not only ON-OFF capabilities but you can precisely time your exposure.
