I'm looking for the subject reed relay to fix a Solartron 7150Plus DMM. It's a single pole encapsulated relay, normally open, pin 1 end with 0.3" spacing, and switch contacts at the other end with 0.2" spacing, the distance between the two sets of pins is 1.0". The coil is driven with a 15V supply. The current Coto model that seems closest is the 3501, but that is 5V or 12V only. Please contact me off list if you can help - I will post again if I get a result. Thanks Dave
