Strange question. Unless you're doing theoretical calculations or simulations only, in most instances you will be working with electronics gear, regardless of the field you go into ... electronics is pervasive. [Strictly, simulations require electronic computers, but I'm not counting that.] Very few equipment these days is entirely mechanical, so electronics will be used in the control and operation of the equipment or for data acquisition. So a background in electronics engineering should hold you in good stead.
Even if you're majoring in physics, it's important to have some exposure to engineering. Physics (at least in the lower levels) focusses on ideal model systems to develop an understanding of fundamental principles. Real systems are often far more complex and are often approached via practical, pragmatic, phenomenological methods, as taught in engineering. A combo of physics and engineering gives you a more comprehensive approach to attacking problems.
