Now *that* confused me! (Although it may be I've taken too much Prozac today!) What are being called "3-way" and "4-way" switches I would call both of them "2-way" switches, as they both only have "On" and "Off" positions. I suppose I might say "3-terminal" or "4-terminal" switches, or more likely "single-pole double throw" and "double-pole double throw" (SPDT and DPDT) but not 3-way and 4-way. Is it just me and the Prozac having an off day? Are such switches actually called "3-way" and "4-way" everywhere (including here in the UK)? If so, I must get out more... :-) Regards, Alan Regards, Alan -- Principal Engineer, BAE Systems Limited, Integrated System Technologies, North Way, Hillend Ind.
