The front panel measures 4-1/4" square, and it is 6" deep excluding the terminal threads.
None have been electrically tested, but all appear to have free-moving indicators.  There appears to besome light overspray on them, but I've made no attempt to clean or operate.
They are all of very heavy duty construction, with significant heft for their size.
